Basic Concepts,y, meros-part.) In this context, a large molecule is commonly arbitrarily regarded either as one having a molecular weight of at least 1000 or as one containing 100 structural units or more. By a structural unit is meant a relatively simple group of atoms joined by covalent bonds in a specific spati

Polyolefins,ule. Polymers derived from unsaturated aromatic hydrocarbons and dienes are considered in later chapters. At the present time the principal commercial polyolefins are polyethylene (polythene), polypropylene, polyisobutene, poly-butene and poly(4-methyl-l-pentene) together with related copolymers. Th

Aromatic polyethers are considered in Chapter 12. Also included in this chapter are furan polymers, which may be regarded as cyclic polyeth
