Question

An example of chain-growth polymer is:

• A. Nylon - $6,6$
• B. Bakelite
• C. Terylene
• D. Teflon

Answer 1

The correct option is D Teflon

Chain-growth polymerization or chain polymerization is a polymerization technique where unsaturated monomer molecules add onto the active site of a growing polymer chain one at a time. Growth of the polymer occurs only at one (or possibly more) ends. Addition of each monomer unit regenerates the active site.

Polyethylene, polypropylene, polyvinyl chloride (PVC) and teflon are common types of plastics made by chain-growth polymerization.

Hence, option D is correct.
