Abstract:
A polyether copolymer having a weight-average molecular weight of 10.sup.4 to 10.sup.7 which may optionally be cross-linked and which comprises:(A) 1 to 99% by mol of a repeating unit derived from a monomer represented by the formula (I): ##STR18##wherein R.sup.1 represents a divalent organic group selected from the group consisting of--CH.sub.2 --O--(CHA.sup.1 --CHA.sup.2 --O).sub.n --CH.sub.2 --,--CH.sub.2 --O--(CH.sub.2).sub.n --,--CH.sub.2 --O--(O)C--(CH.sub.2).sub.n --,--(CH.sub.2).sub.m --CO.sub.2 --(CH.sub.2).sub.n --, and--(CH.sub.2).sub.m --O--CO.sub.2 --(CH.sub.2).sub.n --,wherein A.sup.1 and A.sup.2 each is hydrogen or a methyl group, n is a number of from 0 to 12 and m is a number of from 0 to 6,(B) 99 to 1% by mol of a repeating unit derived from a monomer represented by the formula (II): ##STR19##and(C) 0 to 15% by mol of a repeating unit derived from a monomer having one epoxy group and at least one reactive functional group.
