ABSTRACT:
Polyether represented by R(—O—Xn—Zm—Y)p{R is a monovalent hydrocarbyl group that contains no more than 20 carbon atoms and that may contain an aliphatically unsaturated bond or is a group comprising the preceding group having an ether linkage therein; n is 1 to 200; m is 0 to 200; 0<n/(n+m) ≦1; X is a group provided by the ring-opening polymerization of a glycidyl ether; Z is an alkyleneoxy group having 2 to 6 carbon atoms; p is 1 to 6; Y is H or is a monovalent hydrocarbyl group, acyl group that contains no more than 20 carbon atoms and that may contain an aliphatically unsaturated bond or glycidyl group; and the configuration of the X and Z groups may be, inter alia, random} wherein either R or Y contains or both R and Y contain an aliphatically unsaturated bond and the molecular weight distribution (polydispersity) determined versus a polystyrene standard is 1.25 to 1.00. A method of production in which base catalyst-mediated ring-opening polymerization is carried out on glycidyl ether or glycidyl ether and an alkylene oxide having 2 to 6 carbon atoms in the presence of a monohydric to hexahydric alcohol.
