MOLDED ARTICLE OF RUBBER FOR ROLL AND ITS PRODUCTION

摘要

PURPOSE:To obtain the title molded article having excellent wear resistance, thermal aging resistance and compression set characteristics by molding higher alpha-olefin-based copolymer rubber consisting of a higher alpha-olefin and a nonconjugated diene and vulcanizing. CONSTITUTION:Higher alpha-olefin-based copolymer rubber consisting of 6-12C higher alpha-olefin and a nonconjugated diene shown by the formula (R<1> is 1-4C alkyl; R<2> and R<3> are H or 1-4C alkyl with the proviso that R<2> and R<3> are not H at the same time) and having 1.0-10.0dl/g intrinsic viscosity [eta] measured in decalin at 35 deg.C and 1-50 iodine value is molded and vulcanized to give the objective molded article.
