Abstract

Semi-interpenetrating polymer networks which may be used as printing inks or as coatings are prepared by subjecting a mixture of a vinyl ether and a cellulose ester to irradiation from an electron beam. This mixture is curable with low energy dosages ranging from about 0.1 to about 10.0 Mrads, and from about 150 to about 300 Kev. The reaction is effected in the presence of a polymerization catalyst comprising an onium salt.
