ABSTRACT:
Rubber compositions which, in addition to conventional ingredients of an ethylene-propylene copolymeric rubber, an organopolysiloxane having ethylenically unsaturated linkages, a vulcanizing agent and finely divided reinforcing silica filler, contain an N,N'-alkylenediamine bis-stearoamide eliminate the problem of surface staining of the metal molds repeatedly used to mold the rubber composition caused by the aging retarder therein and thus enough aging retarder can be included therein so that rubber vulcinizates having excellent heat resistance can be prepared from the rubber compositions without creating a surface stain problem.
