Crystallisation of polymers is an undesirable property. Crystallisation of celluloid is prevented by adding_________________?
Correct answer: C. Camphor
- A. Glycerol
- B. Nitro cellulose
- C. Camphor
- D. None of these
Explanation
Celluloid is cellulose nitrate plasticised with camphor, which reduces intermolecular attraction and suppresses crystallisation, making the material flexible. Nitrocellulose is the base polymer, not the crystallisation-preventing additive.
