What do the "big six" polymers have in common?
A)They all are formed by addition polymerization
B)They all are formed by condensation polymerization
C)They all are thermoplastics (can be melted and shaped)
D)They all contain branched chains

Question

Quizplus · Accepted Answer

The "big six" polymers, which include polyethylene, polypropylene, polystyrene, polyvinyl chloride, polyethylene terephthalate, and polymethyl methacrylate, are all thermoplastics. This means that they can be melted and shaped repeatedly without losing their inherent properties. Additionally, they are all formed by addition polymerization. While some of them may contain branched chains, this is not a universal characteristic shared by all of them.  Therefore, option C is the best choice.
