Abstract

PURPOSE: The present invention provides a resin composition which can be used in cross-linking of rubber and in dynamic cross-linking of thermoplastic elastomers, wherein it is easy to handle and can yield homogeneous cross-linking, and can improve compression set and molding processability of a cross-linked elastomer composition obtained by cross-linking, such as cross-linked rubber compositions and cross-linked thermoplastic elastomer compositions. CONSTITUTION: The resin composition according to the present invention comprises (a) 100 parts by weight of at least one compound selected from the group consisting of phenolic resins and brominated phenolic resins, (b) 20 to 500 parts by weight of a crystalline olefine resin other than copolymers of ethylene with an unsaturated carboxylic acid ester or with vinyl acetate, (c) 20 to 300 parts by weight of a non-aromatic softening agent for rubber, and (d) 10 to 100 parts by weight of at least one polymer selected from the group consisting of a copolymer of a vinyl aromatic compound with a conjugated diene compound, a hydrogenated copolymer obtained by hydrogenating said copolymer, and a hydrogenated polymer obtained by hydrogenating a polymer of a conjugated diene compound.
