ABSTRACT OF THE DISCLOSURE It is known to prepare polymers by reaction acids containing an unsaturation with polyepoxides. Such methods involve the use of hazardous or toxic monomers. However, the resultant polymers have a wide industrial utility. The present invention seeks to overcome the disadvantages of the monomers by partially proreacting the monomers to reduce the industrial hazard. The present invention provides a process for producing a radiation curable resin which comprises reacting a) a vinyl polymer comprising in polymerized form about 2 to 20 weight percent of a vinyl acid and the balance to make 100% of one or more copolymerizable monovinyl monomers, b) an unsaturated monocarboxylic acid, and c) a polypeptide having more than one 1,2-oxirane group per molecule; wherein the total acid equivalents per oxirane group is from about 0.8 to 1.2 acid and wherein a) comprises from about 1 to 10 percent of the total acid equivalents.
