Solution:
- (d) Thermosetting polymers undergo chemical changes when heated and set to hard mass when cooled e.g. Bakelite.

Thermoset plastics contain polymers and cross linked together during the curing process to form an irreversible chemical bond. Cross linking process making thermosets plastic ideal for high heat applications.
