PURPOSE:To obtain the titled composition, containing an organic peroxide and biphenyltetracarboxydiimide compound, capable of preventing radical scission of rubber backbone chains and improving crosslinking efficiency of rubber, heat resistance and elastic modulus on high temperature sides. CONSTITUTION:The aimed composition obtained by containing preferably 1-5 pts.wt. organic peroxide (e.g. tert-butyl hydroperoxide) and preferably 1-10pts. wt. biphenyltetracarboxydiimide compound expressed by formula I or II (R is allyl) (e.g. 2,3,3',4'-biphenyltetracarboxy-N,N'-diallyldiimide) in 100pts.wt. rubber. Furthermore, the compound expressed by formula I or II is synthesized from 2,3,3',4'-biphenyltetracarboxylic acid dianhydride or 3,3',4,4'-biphenyl tetracarboxylic acid dianhydride and allylamine (e.g. 2-propenylamine).
