Method for the preparation of mixtures of (meth)acrylic terminated polyether resin and 3-halo-2-hydroxypropyl (meth)acrylate

Claim 1

In the method of preparing a mixture of a resin represented by the formula: and a reactive solvent represented by the formula: ##STR7## wherein (a) said reactive solvent constitutes from about 5 percent to about 95 percent by weight of said mixture; (b) diglycidyl ether of bisphenol A represented by the formula: ##STR8## and epihalohydrin represented by the formula: ##STR9## are reacted with ethylenically unsaturated monocarboxylic acid which is acrylic acid, methacrylic acid or mixtures of acrylic acid and methacrylic acid; (c) the average value of n is in the range of from 0 to 3; (d) the average values of a, b and c are each independently in the range of from 0 to 1; (e) the average value of d is in the range of from 0 to 1; (f) the average value of e is in the range of from 0 to 1; (g) d + e = 1; (h) the average value of f is in the range of from 0 to 1; (i) the average value of g is in the range of from 0 to 1; and (j) f + g = 1 the improvement comprising adding said diglycidyl ether of bisphenol A and said epihalohydrin to said ethylenically unsaturated monocarboxylic acid while the weight of said reactive solvent in the reaction mixture is at least about 5 percent of the sum of the weights of said resin and said reactive solvent present in said reaction mixture.
