ABSTRACT:
A stable aqueous emulsions of epoxy resins are provided using an epoxy-functional polyether having the formula: ##STR1## wherein R.sup.1 is a C.sub.1 -C.sub.15 alkyl, aryl or alkylaryl group, R.sup.2 is a divalent aliphatic group, a divalent cycloaliphatic group, a divalent aryl group, or a divalent arylaliphatic group, R.sup.3 is independently a hydrogen or a C.sub.1 -C.sub.10 alkyl group, R.sup.8 is a divalent aliphatic group optionally containing ether or ester group(s) or together with R.sup.9 or R.sup.10 form a spiro ring optionally containing heteroatoms, and R.sup.9 and R.sup.10 are independently hydrogen or R.sup.9 or R.sup.10 together with R.sup.8 form a spiro ring optionally containing heteroatoms such as oxygen, r is a real number from about 0 to about 6, X and Y are independently a hydrogen, methyl or ethyl group with the provision that if X is methyl or ethyl, Y is hydrogen or if Y is methyl or ethyl, X is hydrogen and n+m is a real number from about 15 to about 450 and n is a real number in an amount effective to provide emulsifying property.
