Abstract
Abstract Water-borne thermoplastic polyhydroxyether resins are prepared by grafting carboxyl-containing vinyl monomers onto phenoxy resins with a free radical initiator and then converting the graft copolymer to an ionomer suitable for use as coatings or adhesives.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
155 words
Method of preparing thermoplastic polyhydroxyethers which can be dispersed in water which comprises: (1) grafting onto normally solid thermoplastic polyhydroxyether one or more ethylenically unsaturated hydrocarbon monomers having 3 to about 8 carbons at least one of said monomers containing sufficient carboxyl, --COOH, groups to provide from about 1 carboxyl group per 10 monomeric units of thermoplastic polyhydroxyether to about 10 carboxy groups per each monomeric unit of polyhydroxyether; and (2) blending said grafted thermoplastic polyhydroxyether in a high turbulence field with: (a) water, (b) a water-miscible base, and (c) a water-miscible organic solvent in which said thermoplastic polyhydroxyether is soluble until an ionomer of the grafted thermoplastic polyhydroxyether is obtained as a colloidal dispersion, said thermoplastic polyhydroxyether having the general formula: --D--O--E--O--.sub.n wherein D is the radical residuum of a dihydric phenol, E is an hydroxyl containing radical residuum of an epoxide and n represents the degree of polymerization and is at least 30.
Claim 2
Dependent Claim
