Abstract: PURPOSE:To obtain the titled composition, useful as shock-proof materials, e.g. shoe sole, etc., and capable of providing low impact resilience with low hardness as well as high strength, by blending polynorbornene with oils compatible therewith, unsaturated carboxylic acid, Mg , rubber reinforcing agent and peroxide. CONSTITUTION:A composition, obtained by blending (A) 100pts.wt. polynorbornene with (B) 180-400pts.wt. oils, e.g. aromatic oil, etc., compatible with the component (A), (C) 5-20pts.wt. 3-8C alpha,beta-monoethylenically unsaturated carboxylic acid, e.g. acrylic acid, etc., (D) 3-60pts.wt. rubber reinforcing agent or filler, e.g. silica, etc., and (E) 1-8pts.wt. peroxide, e.g. dicumyl peroxide, etc., and further (F) magnesium ions to given an equivalent amount or more based on the existing carboxylic acid groups and having 5-45 hardness after crosslinking measured by a JIS-A type hardness meter.

Abstract: PURPOSE:To obtain the title molding excellent in low-temperature impact resistance, strength and resistance to solvent cracking, by irradiating an ionomer resin molding with a radiation. CONSTITUTION:A molding formed by molding an ionomer resin formed by neutralizing a copolymer of a monoolefin with 4-30wt% 3-8C unsaturated mono- or di-carboxylic acid (ester) with a metal such as Na, K or Li into a molding such as a film sheet, a ball for a ball game, a batting tool for a ball game, a yarn or a string for sporting goods is irradiated with a radiation (e.g., cobalt 60) at a dosage >=1 Mrad.

Abstract: A solid golf ball is prepared using a rubber composition comprising a microencapsulated zinc salt of allyl group containing carboxylic acid, which is uniformly blended into a rubber to bring an excellent impact resilience in the golf ball. Further, the rubber composition comprising the microencapsulated zinc salt has little tendency to stick to a roll at the kneading of the rubber composition.
