The poly(alkylene oxide)s are linear or branched-chain polymers that contain ether linkages in their main
polymer chain structure and are derived from monomers that are vicinal cyclic oxides, or epoxides, of
aliphatic olefins, principally ethylene and propylene and, to a much lesser extent, butylene. These polyethers
are commercially produced over a range of molecular weights from a few hundred to several million for use
as functional materials and as intermediates. Lower polymers are liquids, increasing in viscosity with
molecular weight. The high polymers can be thermoplastic. Solubilities range from hydrophilic water-soluble
polymers that are principally derived from ethylene oxide, to hydrophobic, oil-soluble polymers of propylene
oxide and butylene oxide. A wide variety of copolymers is produced, both random copolymers and block
copolymers. The latter may be used for their surface-active characteristics.
