ABSTRACT:
A stable aqueous emulsions of epoxy resins are provided using an epoxy-functional polyether having the formula: ##STR1## wherein Q is A or B, R.sup.1 is independently a divalent hydrocarbon group, R.sup.2 is a divalent aliphatic group optionally containing ether or ester groups or together with R.sup.3 or R.sup.4 form a spiro ring optionally containing heteroatoms, and R.sup.3 and R.sup.4 are independently hydrogen or R.sup.3 or R.sup.4 together with R.sup.2 form a spiro ring optionally containing heteroatoms such as oxygen, X and Y are independently 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+o is a positive real number from about 15 to 450, and where Q is B, n+o is a real number in an amount effective to provide emulsifying property.
