Abstract

Chemically modified thickenable vinyl esters prepared by reacting an ethylenically unsaturated monocarboxylic acid with a polyepoxide in the presence of a small amount of a dicarboxylic acid. These resins are usually diluted with a copolymerizable monomer such as styrene, blended with a Group II metal oxide or hydroxide and other additives, and cured with a free-radical catalyst.
