Polythene is an addition homopolymer of a single monomer, ethene, $\text{CH}_2{=}\text{CH}_2$ . Nylon-6,6 is a condensation polymer of two monomers: hexamethylenediamine, $\text{H}_2\text{N--}(\text{CH}_2)_6\text{--NH}_2$ , and adipic acid, $\text{HOOC--}(\text{CH}_2)_4\text{--COOH}$ . Terylene is a condensation polymer of ethylene glycol, $\text{HO--CH}_2\text{CH}_2\text{--OH}$ , and terephthalic acid, $p\text{-HOOC--C}_6\text{H}_4\text{--COOH}$ . Bakelite is a condensation polymer of phenol, $\text{C}_6\text{H}_5\text{OH}$ , and formaldehyde, $\text{HCHO}$ . Natural rubber is biosynthesised, as cis-1,4-polyisoprene, from repeated addition of …
