Question

What are Polymers? Give the name of two polymers and their uses.

Answer 1

Polymers are macromolecules having high molecular weights and composed of smaller repeating units called monomers. The term polymer is derived from Greek roots 'poly' means 'many' and 'meros' means 'part'.
(1) Acrylonitrile (A), butadiene (B) and styrene (S) combine together to form ABS plastic (a polymer) which is tough, strong and used to prepare articles which withstand heavy impacts.
(2) Vinylidene chloride and vinylchloride form a polymer used as a film for wrapping food (polymer is called saran).
