Question
Which of the following are addition polymers?
(i) Nylon
(ii) Melamine formaldehyde resin
(iii) Orlon
(iv) Polystyrene
Solution
(iii) Orlon
(iv) Polystyrene
Explanation:
The addition polymers are formed by the repeated addition of monomer molecules possessing double or triple bonds, e.g., the formation of polythene from ethene and polypropylene from propane. However, the addition polymers formed by the polymerisation of a single monomeric species are known as homopolymers.
