MODIFICATION OF NATURAL RUBBER LATEX BY IRRADIATION

摘要

PURPOSE:To decrease the dose necessary for modification, by adding methyl methacrylate and CCl4 to a natural rubber latex and irradiating the mixture with an ionizing radiation. CONSTITUTION:0.5-10pts.wt. CCl4 and 25-200pts.wt. methyl methacrylate are added to 100pts.wt. (in terms of rubber solid) natural rubber latex, and the obtained mixture is agitated for 30min or longer, kept at 20-50 deg.C and irradiated with an ionizing radiation at a dose of 0.5-10kGy within 20hr.
