摘要

Reported in this article are results of experiment in which diandtri-methacrylic acid esters and di- and tri-allyl compoundsare used as cross linking monomer to coat P.M.M.A., irradiatedwith radioactivity to bring about linking reaction and improvementin linking density, so that the abrasion resistance of the dentalP.M.M.A. can be improved.It was found that to add diallyl compound to unsaturated polyesterand to coat the material with curing catalyzer as coatingmaterial added with M.E.K.P.O. and naphthenic acid cobalt and toirradiate with radioactivity to enrich cross linking density afterhot press processing were very effective as a treatment to improveabrasion resistance of dental P.M.M.A ..
