Free Polymers MCQs with Answers
72 Polymers MCQs from Chemistry, each with the correct answer and a written explanation of why it is correct. Free and unlimited, with no account needed.
Polymers are large molecules made from repeating monomer units joined by covalent bonds. The topic distinguishes addition polymers such as polyethylene, PVC and polystyrene from condensation polymers such as nylon and polyester, and relates chain structure to thermoplastics, thermosetting polymers, elastomers, properties, uses and environmental concerns.
