Abstract

A composition which on vulcanizing exhibits increased reinforcement contains natural or synthetic rubber and a proportion, e.g. 5 to 25%, based on the total weight, of isotactic polypropylene, i.e. any solid polymer of propylene which consists mainly of crystalline polypropylene. Polypropylenes of melt viscosities at 190 DEG C. between 104 and 105 poises and at least 70% by weight, insoluble in hot heptane, are preferred. Specified synthetic rubbers are copolymers of butadiene and styrene or acrylonitrile, copolymers of isoprene and isobutylene, and polymers and copolymers of chloroprene. Examples are concerned with vulcanizable natural rubber compositions containing as antioxidant bis - (2 - hydroxy - 3 - t - butyl - 5 - methyl phenyl) methane or bis-(2-hydroxy-3-alpha - methylcyclohexyl - 5 - methyl phenyl) - methane and vulcanizable compositions containing an isobutylene-isoprene copolymer, and a copolymer containing 75% butadiene and 25% styrene.
