Abstract

754,514. Vulcanized synthetic rubber. HERCULES POWDER CO. Sept. 22, 1954 [Dec. 31, 1953; June 9, 1954], No. 27449/54. Class 2 (5). [Also in Group V] A vulcanized synthetic rubber product is prepared by vulcanizing a composition comprising a synthetic rubber and from 0.1 to 10 per cent based on the weight of the rubber of a di-(aralkyl) peroxide having the formula: where R 1 is an aryl group; R 2 , R 3 , R 4 and R 5 are hydrogen or an alkyl group of less than 4 carbon atoms; and R 6 is an aryl group. Specified synthetic rubbers are polymers of butadiene, isoprene, dimethyl butadiene and 2-chlorobutadiene and copolymers of butadiene or isoprene with styrene or acrylonitrile. The peroxide may be unsymmetrical, e.g. benzyl- (α - methyl - benzyl) peroxide and benzyl- (α - methyl - p - methylbenzyl) peroxide, or symmetrical, e.g. bis-(α,α-dimethyl-p-methylbenzyl) peroxide; bis-(α,α-dimethyl-p-isopropyl) peroxide, and bis-(α,α-dimethylbenzyl) peroxide. The di-(aralkyl) peroxide may be used with tetraethylene pentamine as accelerator and tetrahydroabietate as activator. Known antioxidants e.g. diphenylamine, may be added.
