Answer 2

Explanation:

to their chemical composition, their physical properties, and their general application. For each of these three categories, name two examples that that might be considered when adapting a polymer to a particular end-use.

and a thermoset, and comment on the molecular basis for their different properties, including crystallinity.

Describe the two general methods of polymer synthesis.

Name two kinds each of commercially-important synthetic thermoplastics and thermosets, and specify some of their principal uses.

Name two kinds of commercially-important natural polymers.

Describe some of the concerns and sources of small-molecule release from polymers.

What are some of the problems connected with recycling or re-use of polymeric materials?
