Question

What do you mean by the term "polymer" ?​

Answer 1

$\huge \red{ \mathcal{ \underline{Answer:}}}$

• A synthetic fibre has a chain of many small units joined together. These small units are called monomers and the chain formed by joining many more monomers together is known as a polymer. Thus, polymers are large molecules consisting of a large number of small molecules called monomers.

• The process of linking monomers to form polymers is called polymerization. The word poly means 'many' and mer means 'repeating units' in Greek.

• Polythene (or polyethylene) is a polymer which is used to make carry bags. It is a polymer of ethene. That is, polythene is formed when a large number of ethene molecules (monomers) link up.

• Polymers are of two types, natural and synthetic. Those polymers which occur in nature are called natural polymers. For example, cotton is a natural polymer of cellulose (wood pulp), Silk, wool, proteins, etc., are some other natural polymers.

• Polymers which are separated artificial from small molecules are called synthetic or man-made polymers. For example, Rayon, Nylon, Polythene, Teflon etc.

• Most synthetic polymers are strong, light in weight and long-lasting, which make them very useful. They are used extensively to make fabric, pipes, buckets, classes, packaging, material, etc

Answer 2

polymer is a useful chemical made of many repeating units.
