Abstract

1523850 Free-flowing rubber mixtures BAYER AG 30 June 1977 [2 July 1976] 27399/77 Headings C3L and C3M Free-flowing rubber mixtures comprise (1) a vulcanizable rubber in powder form and (2) 3-12% by weight of the rubber of polyacrylonitrile. The polyacrylonitrile may be incorporated by grinding or during precipitation or spray-drying. Exemplified rubbers are ethylene/ vinyl acetate copolymers, copolymers of butadiene with styrene or acrylonitrile and polychloroprene.
