Polymers are large macromolecules composed of repeated subunits called monomers. They are one of the most important classes of materials and are used in a wide range of applications, including plastics, fibers, and coatings.
Here are some important concepts related to polymers that you should know as a JEE (Main+Advance) e-Intermediate Course student:
- Polymerization: Polymerization is the process by which monomers are chemically bonded together to form a polymer. There are two main types of polymerization: addition polymerization and condensation polymerization.
- Types of Polymers: There are three types of polymers: thermoplastics, thermosets, and elastomers. Thermoplastics are polymers that can be melted and re-molded multiple times, while thermosets are polymers that become rigid and cannot be re-molded after they are formed. Elastomers are polymers that have the ability to stretch and return to their original shape.
- Polymer Properties: The properties of a polymer are determined by its chemical structure and the way its molecules are arranged. Some important properties of polymers include mechanical strength, thermal stability, chemical resistance, and electrical conductivity.
- Polymer Processing: Polymer processing refers to the methods used to transform raw polymer materials into finished products. Some common processing methods include injection molding, extrusion, blow molding, and thermoforming.
- Polymer Additives: Additives are substances added to polymers to improve their performance or to impart specific properties. Some common additives include plasticizers, stabilizers, pigments, and fillers.
Overall, polymers are an important topic in materials science and engineering, and a good understanding of their properties and processing methods is essential for many industries.

Production of JEE (Main+Advance) e-Intermediate Course Polymers
The production of polymers involves several steps, including polymerization, processing, and shaping. Here is a general overview of the production process for polymers:
- Polymerization: The first step in the production of polymers is polymerization, which involves the chemical reaction of monomers to form polymer chains. There are two main types of polymerization: addition polymerization and condensation polymerization. Addition polymerization involves the addition of monomers to a growing polymer chain, while condensation polymerization involves the elimination of a small molecule, such as water, to form a polymer chain.
- Processing: After polymerization, the resulting polymer is typically in the form of a powder or pellet. The polymer may need to be processed further to improve its properties or to make it easier to handle. Common processing methods include extrusion, injection molding, blow molding, and thermoforming.
- Shaping: Once the polymer has been processed, it can be shaped into its final form. This may involve cutting, stamping, or machining the polymer to the desired shape.
- Finishing: After shaping, the polymer may undergo further treatment to improve its properties, such as surface treatments or coatings.
- Testing: Finally, the polymer is tested to ensure that it meets the required specifications for its intended use. This may involve testing for properties such as mechanical strength, thermal stability, and chemical resistance.
In the JEE (Main+Advance) e-Intermediate Course in Polymers, students learn about the different types of polymers, the mechanisms of polymerization, and the processing and shaping methods used in the production of polymers.

Case Study on JEE (Main+Advance) e-Intermediate Course Polymers
One potential case study for the JEE (Main+Advance) e-Intermediate Course in Polymers could be the development of biodegradable polymers for use in packaging.
Plastics are widely used in packaging, but they can take hundreds of years to decompose, leading to significant environmental problems. Biodegradable polymers, on the other hand, can decompose relatively quickly, making them a more environmentally friendly alternative.
In the case study, students could be asked to research and develop a biodegradable polymer for use in packaging. They would need to consider factors such as the type of monomers to be used, the polymerization method, and the processing and shaping methods required. They would also need to consider the properties of the polymer, such as its mechanical strength, thermal stability, and biodegradability.
Students could work in teams to develop their polymers and test them using various methods, such as tensile testing, differential scanning calorimetry, and biodegradation testing. They could then present their findings to the class and discuss the advantages and disadvantages of their polymer compared to other biodegradable polymers and conventional plastics.
This case study would allow students to apply the knowledge they have gained in the JEE (Main+Advance) e-Intermediate Course in Polymers to a real-world problem. It would also encourage critical thinking and collaboration skills, as well as developing an awareness of environmental issues and the role of polymers in society.
