In step growth polymerisation, condensation occurs in a stepwise manner with or without the elimination of smaller molecules. An example of step growth polymerisation product is________________?
Correct answer: A. Terylene
- A. Terylene
- B. Polybutadiene
- C. PVC
- D. Polypropylene
Explanation
Terylene is a polyester formed by step-growth condensation of ethylene glycol and terephthalic acid or a related ester, with elimination of a small molecule. Polybutadiene, PVC and polypropylene are chain-growth addition polymers.
