PCT No. PCT/EP95/05177 Sec. 371 Date Jun. 12, 1997 Sec. 102(e) Date Jun. 12, 1997 PCT Filed Dec. 22, 1995 PCT Pub. No. WO96/20246 PCT Pub. Date Jul. 4, 1996Rubber compositions are provided having improved physical properties. More particularly, the present invention relates to sulfur-vulcanized rubber compositions which are vulcanized in the presence of certain bis-succinimide coagents, which possess anti-reversion and/or accelerating properties. The invention also relates to a sulfur-vulcanization process which is carried out in the presence of one or more bis-succinimide coagents, and to the use of bis-succinimide coagents in the sulfur-vulcanization of rubber. Finally, the invention relates to rubber products comprising rubber vulcanized with sulfur in the presence of one or more bis-succinimide coagents.
