Distinguish between ‘chain growth potymerisatlon and step growth polymerisation’ and give one example of each.

Answer»

Chain growth polymerisation

1. Only one repeating unit is added at a time.

2. Reaction is fast and polymer is formed at once.

Example – polythene.

Step growth polymerisatlon

1. Any two species present can react.

2. Polymer is formed in gradual steps.

Example – Nylon-6, 6
