Examples of synthetic polymer (X) and semi-synthetic polymer (Y) are x

Step-by-step solution

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.
