METHOD OF PREPARING CARBOXYL GROUP-MODIFIED POLYHYDROXYETHERS, PREPARING AN AEQUOUS COLLOIDAL IONOMER DISPERSION THEREFROM, AND THE USE OF THE DISPERSION AS PROTECTING COATING COMPOSITION

摘要

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.
