  • 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.
