(a) thermoplastic
(b) polyester
A number of glucose units make in the nolymer
(c) thermosetting plastic
(d) nylon​

Answer 1

Answer:

Bakelite or polyoxybenzylmethylenglycolanhydride was the first plastic made from synthetic components. It is a thermosetting phenol formaldehyde resin, formed from a condensation reaction of phenol with formaldehyde. It was developed by the Belgian-American chemist Leo Baekeland in Yonkers, New York, in 1907. Wikipedia

Formula: (C6-H6-O.C-H2-O)x

Density: 1.3 g/cm³
