Phosphates (e.g., tricresyl, tributyl, tetrabutyl, triphenyl etc.) are added to polymers to act as __________________?
Correct answer: C. Plasticisers
- A. Hardeners
- B. Anti-shrinkage agents
- C. Plasticisers
- D. Transparency improver
Explanation
Phosphate esters such as tricresyl phosphate and triphenyl phosphate act as plasticisers by lowering the effective rigidity of polymer chains. This improves flexibility and processability.
