Answer 2

Explanation:

1) There are two main types of plastics and these are named Thermoplastics and Thermosetting Plastics. Thermoplastics are made up of lines of molecules with few cross linkages.

2) Other examples of thermoplastics are polypropylene, polystyrene, cellulose acetate, PTFE (Teflon), nylon, polyketone, etc. Polypropylene is also known as polypropene.

3) Examples of thermosetting polymers include:

1) Vulcanized rubber.

2) Bakelite.

3) Polyurethane.

4) Epoxy resin.

5) Vinyl ester resin.
