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.
Claims33
A polymerizable composition comprising a mixture of a vinyl ether, a cellulose ester, and a polymerization catalyst comprising an onium salt.
A polymeric composition comprising a semi-interpenetrating polymer network of a polyvinyl ether and a cellulose ester.
A process for the preparation of a polymeric composition comprising a semi-interpenetrating polymer network of a polyvinyl ether and a cellulose ester which comprises subjecting a mixture of at least one vinyl ether and a cellulose ester to irradiation from an electron beam at low dosages in the presence of a polymerization catalyst comprising an onium salt at polymerization conditions and recovering the resultant semi-interpenetrating polymer network composition.
