In step growth polymerisation, generally only one type of reaction & some basic mechanism is involved. Step growth polymerisation reaction is not involved in the manufacture of__________________?
Correct answer: A. Cross linked polystyrene
- A. Cross linked polystyrene
- B. Phenol formaldehyde resins
- C. Polyesters
- D. Polyamides
Explanation
Cross-linked polystyrene is normally produced by chain-growth addition polymerisation of styrene with a cross-linking agent such as divinylbenzene. Phenol-formaldehyde resins, polyesters and polyamides are typical step-growth products.
