Abstract

A vulcanizable composition comprises, to each 100 parts of an elastomer exemplified by natural rubber, butadiene-styrene and butadieneacrylonitrile copolymers, polychloroprene and butyl rubber, 0,1 to 5 parts of a synthetic polymer containing carboxyl groups in the free state or as salt or anhydride, 1 g. of such polymer being equivalent to at least 15 ml. of 0,1 n sodium hydroxide solution. The synthetic polymers do not include the vinylic fillers of Specification 799,043, and are exemplified by polyacrylic acid, polymethacrylic acid, saponified polyacrylonitrile, methacrylic acid-maleic anhydride copolymer, and copolymers, generally, of a hydrocarbon vinyl monomer with a vinyl acid, maleic anhydride or any unsaturated copolymerizable acid. The composition may be obtained by coagulation of a blend of the synthetic polymer with the elastomer in latex form. The preferred vulcanization accelerators are amines, exemplified by mono (alpha cyanoethyl) tetraethylene pentamine and di (alpha cyanoethyl) diethylene triamine. Reinforcing agents in the compositions are: carbon black, silica, silicates, clays, diatomaceous earth, titania, lignin. Specifications 734,504 and 841,159 are referred to.
