JEE Main Polymers Revision Notes - PDF Download

You will learn about polymers, their classification based on their source, their structure, mode of polymerization, growth polymerization, molecular forces, addition polymerization or chain-growth polymerization, types of polymerization reactions, step-growth polymerization or condensation polymerization, copolymerization, molecular mass of polymers, rubber, and the commercial importance of polymers in everyday life in JEE Main Revision Notes on Polymers.

Following that, JEE Main Revision notes on Polymers will assist students in gaining a better understanding of the subject and learning more about problem-solving skills, allowing them to achieve better results in their final examinations.

JEE Main Revision Notes on Polymers

Ploymers are a kind of polymer that may be used to make a cup  and saucers, plastic buckets, children's toys, synthetic clothing materials, packing bags, automotive tyres, electrical insulating materials, gears and seals, and machine parts are all manufactured with polymers.   Notes Booster's Polymers JEE Main Revision Notes made the idea of polymers simple for students. You will comprehend the core ideas and vocabulary with these JEE Main Revision notes. We've put up these Revision Notes for the Jee Main test, which go over all of the fundamentals in great depth.

These Revision Notes were meticulously developed by our professional team of teachers, who defined the concepts more clearly to aid your learning process. If you have any questions while learning, we have a team of professors that are happy to answer them.

Polymers are made up of numerous molecules linked together by a continuous chain. These are joined together or with a non-polymer molecule, or both, via a covalent connection. The term "biopolymer" refers to natural polymers. They are present in nature and are created by living creatures, the majority of which are plants. Starch, cellulose, proteins, and DNA are all examples of biopolymers. Natural polymers can also be produced as petroleum-based polymers from petroleum sources.

Artificial or man-made polymers are polymers that have been synthesised from diverse synthetic ingredients. Due to their unique qualities like as toughness, lightweight, non-toxicity, chemical and heat resistance, they have a wide variety of uses. Polythene, polypropylene, polyvinyl chloride (PVC), nylon 66, and ABS are all examples of manmade polymers.

  

Subtopics of Polymers

Let's have a look at the various sub-topics that make up the topic of polymers.

• Classification of Polymers -  You will learn about polymers of high molecular mass substances with a large number of repeating structural units, polymerization, kinds of polymers, and polymer classifications such as linear polymers, natural polymers, branching polymers, synthetic polymers, and more in this topic.
• Types of Polymerization Reactions - You'll learn about addition polymerization, also known as chain-growth polymerization, free radical addition polymerization, anionic polymerization, and cationic polymerization, in this section.
• Molecular Mass of Polymers - You will examine the molecular mass of polymers in this subtopic, which is a polymer sample with a chain of various lengths, hence its molecular mass is always stated as an average molecular mass.
• Biodegradable Polymers - You'll learn about biodegradable polymers including proteins, polysaccharides, nucleic acids, Nylon-2-Nylon-6, Aliphatic polyesters, and more in this subtopic.
• Polymers of Commercial Importance - You'll learn about polymers including polyethene, Bakelite, nylon, rubber, Teflon, polyester, and synthetic rubber, which are used to produce tyres, tableware, and toys, among other things.

IIT JEE Mains Notes on Polymers

• Polymer - Polymers are big molecules with a high molecular weight that are made up of numerous tiny components called monomers.
• Natural Polymers - Plants and animals contain these sorts of polymers.
• Polymerization is the process of forming a polymer from its constituent monomers.
• Synthetic polymers are made in a lab from a natural substance. Nylon six and Buna-S are a couple of examples.
• Addition Polymers - These polymers are made up of numerous linkages and are made up of repeated additions of monomers.
• Condensation Polymers - These are made up of bi- or tri-functional monomer units that are repeatedly condensed.

Polymers Classification Based on Source

Natural Polymers

• Polymers derived from animals or plants are known as natural polymers.
  
• These can be found in nature and are usually derived from plants and animals.
  
• DNA, RNA, Cellulose, Protein, Natural Rubber, and other Natural Polymers are examples.
• Isoprene is a kind of polymer found in natural rubber.
• Proteins, Polysaccharides (Carbohydrates), Natural Rubber, and Nucleic Acids are just a few examples of natural polymers.

Rubber trees' latex will be used to make natural rubber. Chemically, it's known as the isoprene units polymer. Natural rubber is sticky, squishy, and has a limited ability to reshape itself. The lack of cross-linkage between polymeric chains is responsible for these features. Natural rubber is brittle at low temperatures (T283 K) and soft at high temperatures (T> 335 K), and it has a high water absorption capacity, making it a semi-fluid, sticky material. It's also soluble in non-polar solvents and oxidising chemicals attack it radially.
