Polymers prepared by polymerizing alpha, beta-ethylenically unsaturated acids and epoxy compounds and crosslinked products therefrom

摘要

Hydroxyl-containing polymers prepared by reaction of a polymerizable alpha, beta-ethylenically unsaturated carboxylic acid and an epoxy compound containing greater than 5 carbon atoms are disclosed. The polymer is prepared by free radical organic solution polymerization techniques. Synthesis of the polymers by this technique assures multiple hydroxyl functionality in all polymer chains thereby providing good cure response. The polymers are useful as binders in high solids coating compositions. When used with appropriate curing agents, the resultant coatings have good hardness, high gloss and distinctness of image, have good solvent and humidity resistance and are very resistant to acid etching.
