Synthetic polymers are polymers that have been created by humans. They are divided into four groups: thermoplastics, thermosets, elastomers, and synthetic fibres. They are commonly found in a wide range of consumer goods. Synthetic organic polymers are created using a variety of main chains and side chains.
Many synthetic polymers are used in our daily life because they have highly desirable properties such as strength, flexibility, resistivity, chemical inertness, and so on.

Synthetic Polymer Types and Examples
[Click Here for Sample Questions]
So far, numerous synthetic polymers have been produced. Let's have a look at a few synthetic polymers that are commonly used in everyday life.
Nylon
Nylon is a synthetic polymer that is also referred to as polyamides. Nylon is a polymer that is commonly used. Because of its amide backbone, it is more hydrophilic than other polymers. Unlike the pure hydrocarbon polymers that make up the majority of plastics, nylon engages in hydrogen bonding with water.
Polyvinyl Chloride
PVC is utilised in building since it is stronger and less expensive than other materials such as copper or iron. PVC is also used to replace rubber in clothing, electrical wire insulation, and a variety of other uses.
Low-Density Polyethylene
Low-Density Polyethylene polymers are the most common synthetic polymers found in homes. LDPE is a type of thermoplastic that is made from the ethylene monomer.
Polypropylene
Polypropylene, also known as polypropene, is a thermoplastic synthetic polymer used in packaging, labeling, stationery, textiles, plastics, reusable containers, and laboratory equipment.
Thermoplastic Polyurethane, Teflon, Polystyrene, High-Density Polyethylene, Neoprene, and other materials are examples.

Synthetic Polymer Applications
[Click Here for Sample Questions]
- Plastic containers of all shapes and sizes are one of the most prevalent uses of Synthetic Polymers.
- They are more lightweight and cost less than regular containers. We employ synthetic polymers in our daily lives, in everything from clothing to storage to construction materials and children's toys.
- Polymers are also important components of materials used in and on the soil to improve aeration, which is the process of creating air spaces between the soil to increase water and mineral permeability. They also help plants grow and thrive.

Synthetic Polymer Advantages and Disadvantages
[Click Here for Sample Questions]
Synthetic polymers play a vital role in our daily life. They have always made life easier and more convenient in a variety of ways, but they do have a disadvantage. The basic ingredients required to make them may become scarce, and getting rid of synthetic polymers is a difficult and time-consuming process.
Advantages of Synthetic Polymers
- In nature, synthetic polymers are extremely adaptable. They're employed in a variety of situations. The major polymer in superglue is methyl 2-cyanopropenoate, which is something we utilise on a daily basis. When RTV silicone is dried, it hardens and is used to produce gaskets for automobiles. Polyester is a big part of the textile sector, through which we receive a lot of our household things, and nylon is utilised in stockings and ropes.
- Synthetic polymers have a lot of desirable properties, which is a big plus. They have good strength, flexibility, resistivity, chemical inertness, and other properties.
Disadvantages of Synthetic Polymers
- Chemical inertness, or resistance to many types of chemical breakdown, is a desirable property in many synthetic polymers. This same quality also means they last a long time after being discarded, which is extremely detrimental to the environment and should be avoided. If these powerful polymers are not properly disposed of, they can cause a slew of problems.

Things To Remember
- Synthetic polymers are materials made up of long molecular chains (macromolecules) and organic linkages that are made from natural products or raw materials such as oil, gas, or coal.
- Nylon, Polyvinyl Chloride, Low-Density Polyethylene, and Polypropylene are all examples of Synthetic Polymers.
- Synthetic polymers have a lot of desirable properties, which is a big plus. They have good strength, flexibility, resistivity, chemical inertness, and other properties. Chemical inertness, or resistance to many types of chemical breakdown, is a desirable property in many synthetic polymers.
- Poor biocompatibility, the release of acidic breakdown products, poor processability, and early loss of mechanical qualities are all downsides of these polymers in tissue engineering applications.

Sample Questions
Ques: What are some of the drawbacks of synthetic polymers and what is the significance of synthetic polymers? (2 Marks)
Ans: Synthetic polymers are a permanent waste because they are non-biodegradable. Plastic bags and bottles that have been used cannot be disposed of in sanitary landfills. These synthetic waste items are then burned in incinerators, releasing toxic gases and polluting the atmosphere.
The significance of synthetic polymers is that they are used in society because they have numerous desired features such as strength, flexibility, resistivity, chemical inertness, and so on.
Ques: What materials are used in the production of synthetic polymers? What are the three main characteristics of synthetic polymers? (3 Marks)
Ans: Synthetic polymers are made up of carbon-carbon bonds and are typically generated from petroleum oil in a controlled environment. The chemical bonds that hold monomers together are altered by heat and pressure in the presence of a catalyst, leading them to connect with one another.
The three main characteristics of synthetic polymers are high strength or their property of being modulus to weight ratios (lightweight yet comparatively stiff and strong), toughness, resilience, corrosion resistance, lack of conductivity (heat and electrical), color, transparency, processing, and low.
Ques: Is it true that synthetic polymers are made of plastic and is silk a natural fiber or a synthetic polymer? (3 Marks)
Ans: Plastics are synthetic or semi-organic polymers created by using chemicals and condensation to induce molecular bonding in oil or petroleum. Plastics, on the other hand, are wholly man-made, despite the fact that polymers can occur naturally.
Synthetic polymers are created by scientists and engineers from petroleum oil. Nylon, polyethylene, polyester, Teflon, and epoxy are examples of synthetic polymers. Silk, wool, DNA, cellulose, and proteins are examples of naturally occurring polymers.
Ques: Cotton is a synthetic polymer, right? What is the process of making synthetic polymers? (3 Marks)
Ans: Cotton fiber is composed of cellulose, a natural polymer. Cellulose is a polymer made up of a huge number of tiny glucose molecules that are linked together one by one.
The process of making synthetic polymers is described below:
Chemical reactions are known as "polymerizations" make synthetic polymers. Polymerizations have numerous forms, much too many to list here, but they all involve the repeated chemical bonding of individual molecules or monomers. Two or more distinct monomers can be combined to generate co-polymers.
Ques: Is it safe to use synthetic polymer? What is the distinction between natural and synthetic fiber? (2 Marks)
Ans: Synthetic polymers, which may damage the environment and contain potentially dangerous chemicals, are included in many personal care items.
Plants, animals, insects, and other natural elements are used to make natural fibers. They are natural and biodegradable, as well as being uncooked. Wool, cotton, silk, and other natural fibers are examples. Synthetic fibers are formed from synthetic materials and are created through a variety of chemical methods.
Ques: Give an example of an elastomer. (All India 2009, 1 Mark)
Ans: Buna-S and Buna-N.
Ques: What does the '6, 6' part of the name nylon-6, 6 mean? (All India 2009, 1 Mark)
Ans: Nylon '6,6' denotes that it is a condensation polymer of two monomer molecules, each with six carbon atoms, namely adipic acid (HOOC (CH2)4 COOH) and hexamethylenediamine (H2N CH2 CH2 CH2 CH2 CH2 CH2 NH2)
Ques: What is the primary structural feature that a molecule must have in order to be useful in a condensation polymerization reaction? (All India 2009, 2 Marks )
Ans: The presence of two bifunctional monomer molecules causes condensation with the loss of a simple molecule of water, alcohol, resulting in the formation of a dimer.
Ques: What are biodegradable Polymers? (Delhi 2010, 2 Marks)
Ans: Biodegradable Polymers: All these biopolymers which disintegrate by themselves in biological systems during certain period of time by enzym?ti? hydrolysis are called biodegradable polymers.
