Which one of the following is the best classification of an amorphous polymer that is flexible?
A) fibers
B) elastomers
C) plasticizers
D) thermoplastics
E) thermosetting resins

Question

Quizplus · Accepted Answer

Elastomers are amorphous polymers that have a high degree of flexibility due to their ability to stretch and return to their original shape. Unlike thermoplastic polymers, they cannot be melted and reshaped, and unlike thermosetting resins, they do not undergo a chemical reaction to harden. Plasticizers are added to polymers to make them more flexible, but they are not a classification of polymer themselves. Fibers are long and thin polymers that are not typically flexible as they are usually used for their strength and tensile properties.
