CLASS: IC: C08L021-00; C08K005-10. APPLICATION: JP 82-174366 4 Oct 1982. DOCUMENT TYPE: Patent CA Section: 39 (Synthetic Elastomers and Natural Rubber) The compns. are composed of 5-100 parts (meth)acrylic acid higher ester, 100 parts rubber, org. peroxide-vulcanizable and org. peroxide. Thus, SBR 100, TiO2 10, CaCO3 80, stearic acid 1, benzoyl peroxide 1.5 and stearyl acrylate (I) [4813-57-4] 20 parts were press-cured to give rubber sheeting with JIS hardness 62 as compared to 70 when I was not used.
