Question 1
CBSEENCH12009228

What are polymers?

Solution
A substance which has a molecular structure built completely from a large number of similar units bonded together known as polymers. Polymers has high molecular mass. They are also called macromolecules. Some examples of polymers are polythene, bakelite, rubber, etc.
Question 2
CBSEENCH12009229

How are polymers classified on the basis of structure?

Solution

There are three different types based on the structure of the polymers.
(i) Linear polymer: These polymers consist of long and straight chains. Such as polythene, polyvinyl chloride etc.
(ii) Branched chain polymers: These polymers contain linear chains having some branches. Such as low density polythene.
(ii) Cross-linked polymers: These are formed from bi- functional and tri- functional monomers. Such as bakelite, malamin etc.
