IMPARTING LATEX SPONGE RUBBER WITH HYDROPHILICITY BY GRAFT POLYMERIZATION

摘要

PURPOSE:To impart a latex sponge rubber with hydrophilicity, by immersing said rubber in or impregnating said rubber with an aqueous solution of potassium peroxydisulfate and heating followed by immersion in or impregnation with an aqueous solution of polyethylene glycol dimethacrylate and heating. CONSTITUTION:A latex sponge rubber is immersed in or impregnated with a 0.2-5% aqueous solution of potassium peroxydisulfate followed by heating to produce polymer-activating seeds. The resulting rubber is immersed in or impregnated with a 0.2-5% aqueous solution of polyethylene glycol dimethacrylate followed by heating to induce graft polymerization, thus imparting said rubber with hydrophilicity.
