Answer 1

Answer: (A)

Synthetic polymer

Synthetic polymers are human-made polymer they can be classified into four main categories

(i) thermoplastics

(ii) thermosets

(iii) elastomers

(iv) synthetic fibers

e.g. polythene



Semi synthetic polymer

A semi synthetic polymer is a polymer made by chemically treating a natural polymer. e.g. rayon

Rayon is derived from naturally occurring cellulose.
