PURPOSE: A rubber composition, obtained by incorporating a conjugated diene based rubber containing an acenaphthylene based monomer as constituent com ponents, having a high strength and high rigidity and suitable for tires, safety bumpers, etc. n CONSTITUTION: A composition obtained by incorporating ≥5wt%, preferably ≥20wt% diene based rubber, obtained by polymerizing an acenaphthalene based monomer with another conjugated diene monomer or a monomer copoly merizable therewith, e.g. 1,3-butadiene or isoprene, and containing 2W60wt%, preferably 5W40wt% acenaphthylene based monomer and compounding ingredients, e.g. sulfur or vulcanizing assistant, with raw material rubber. n COPYRIGHT: (C)1986,JPO&Japio |
