Abstract

1,263,499. Butadiene-acrylonitrile copolymer compositions. BRIDGESTONE TIRE K.K. 19 May, 1969 [23 May, 1968 (2)], No. 25525/69. Headings C3P and C3Q. A rubbery composition comprises a stereospecific alternate copolymer of butadiene and acrylonitrile, in which the butadiene is bonded in a high trans-1,4-structure and the butadiene unit and acrylonitrile unit are bonded substantially alternately, with 10-150 parts per 100 parts by weight of polymer of an inorganic powder preferably having average particle diameter less than 500 mÁ, e.g. carbon black, finely divided silicic acid and artificial silicate, and/or a rubbery polymer, the weight ratio of the stereospecific alternate copolymer to the rubbery polymer being 5/95-99/1. The rubbery polymer may be natural rubber, styrene-butadiene rubber, butadiene rubber, isoprene rubber, another nitrile rubber, ethylene-propylenediene rubber, chlorosulphonated polyethylene rubber or polysulphide series synthetic rubber. The compositions may be vulcanized and may also contain stearic acid and tricresyl phosphate.
