摘要： A vulcanized rubber composition which is obtained by vulcanizing a modified ethylene-.alpha.-olefin-nonconjugated diene copolymer rubber composition defined below with sulfur or organic peroxides, said modified rubber composition comprising an ethylene-.alpha.-olefin-nonconjugated diene copolymer rubber modified with 0.01-0.15% by weight of an unsaturated carboxylic acid or a derivative thereof on the basis of the modified ethylene-.alpha.-olefin-nonconjugated diene copolymer rubber and at least one dinitroamine represented by the following formula (A): ##STR1## wherein X represents a divalent chain aliphatic, cyclic aliphatic or aromatic group which may contain a halogen or oxygen, R.sup.1 represents a hydrogen atom, a chain aliphatic group, a cyclic aliphatic group or an aromatic group with a proviso that when both X and R.sup.1 represent a chain aliphatic group, nitrogen atoms may further link to each other through R.sup.1, and R.sup.2 and R.sup.3 each represents a hydrogen atom or an alkyl group of 1-12 carbon atoms and R.sup.2 and R.sup.3 may link to each other to form a ring. The vulcanized rubber composition is excellent in fatigue resistance against repeatedly applied deformation.

摘要： An adhesive composition comprising a modified, ethylene/.alpha.-olefin copolymer rubber or a modified, ethylene/.alpha.-olefin/non-conjugated diene copolymer rubber containing 0.1-10% by weight of at least one member selected from the group consisting of an acid anhydride and a dicarboxylic acid, and, if necessary, as an amine compound,(i) 0.2-2 moles of a dialkylamine per mole of the acid anhydride in said modified copolymer rubber when said modified copolymer rubber contains no dicarboxylic acid;(ii) 0.2-2 moles of a polyamine compound per mole of the total amount of the acid anhydride and the dicarboxylic acid in said modified copolymer rubber; or(iii) 0.2-2 moles of a dialkylamine per mole of the acid anhydride in said modified copolymer rubber and 0.2-2 moles of a polyamine compound per mole of the acid anhydride in said modified copolymer rubber when said modified copolymer rubber contains no dicarboxylic acid. The above adhesive composition exhibits good adhesion for rubber compositions, particularly low unsaturated, non-polar rubber compositions and fibers, and is excellent in storage stability.

摘要： A vulcanized, ethylene/.alpha.-olefin copolymer rubber composition obtained by vulcanizing an unvulcanized rubber composition comprising 100 parts by weight of a rubber composition consisting of 0-99% by weight of an ethylene/.alpha.-olefin copolymer rubber and 100-1% by weight of an ethylene/.alpha.-olefin copolymer rubber containing an .alpha.,.beta.-unsaturated carboxylic acid and/or a derivative thereof; and 5-100 parts by weight of a polyamide resin, wherein an ethylene/.alpha.-olefin copolymer rubber is at least one selected from ethylene/.alpha.-olefin copolymers and ethylene/.alpha.-olefin/non-conjugated diene copolymers. The vulcanized, ethylene/.alpha.-olefin copolymer rubber composition of the present invention has a high hardness and is excellent in weather resistance and thermal resistance as compared with natural rubbers and general-purpose rubbers.
