Abstract

PURPOSE: A rubber polymer is combined with a fatty acid or hydrogenated resin and vulcanized with a resin-vulcanizing system to produce the titled composition that inhibits the migration of vulcanizers into the rubber mandrel to keep the durability and prevents the deterioration of the inner rubber layer.
CONSTITUTION: (A) 100pts.wt. of isobutylene and isoprene copolymer or ethylene- propylene-diene terpolymer are combined with (B) 3W20pts. of a fatty acid such as stearic or lauric acid or hydrogenated resin. The resulting resin is incorporated with a vulcanizing system effecting resin vucanization to give the vulcanized product for mandrel.
