B)Copolymers
C)Thermosetting polymers
D)Thermoplastics

Question

Quizplus · Accepted Answer

Thermoplastics refer to polymers that soften when heated and harden when cooled. This is because the individual polymer chains can move and flow when heated, but then become locked into place upon cooling. Cross-linked polymers and copolymers refer to different types of polymerization and do not necessarily have this property. Thermosetting polymers, on the other hand, harden irreversibly upon heating and cannot be softened again upon cooling.
