Abstract

1,159,698. Mastication of 2-alkyl-butadiene- 1,3/acrylic nitrile rubbers. POLYMER CORP. Ltd. 4 Nov., 1966 [5 Nov., 1965], No. 49627/66. Headings C3C and C3P. A vulcanizable composition is produced by masticating a high molecular weight elastomeric copolymer of a 2-alkyl butadiene-1,3 and up to 50 mole per cent of an acrylic nitrile, said copolymer having a Mooney viscosity ML 1+4 (100‹ C.) of at least 40, to produce an essentially gel-free copolymer having a Mooney viscosity ML 1 + 4 (100‹ C.) of below 20. Specified dienes are isoprene and the 2-ethyl 2-isopropyl, 2- amyl and 2,3-dimethyl butadienes. In the examples an isoprene-acrylonitrile copolymer is masticated using conventional peptizers and compounded with vulcanizing agents and other ingredients selected from calcium silicate, silica, carbon black, TiO 2 , triglycol dioctylate, nitrile rubber, SBR rubber and cis - 1,4 polybutadiene prior to vulcanization. In Example VII a closed cell expanded structure is produced by including ammonium bicarbonate or sodium bicarbonate in the composition vulcanized.
