Abstract

PURPOSE: To prepare the titled composition giving a molded article having excellent oil resistance and free from stickiness, by dispersing and reacting a crosslinking agent to a mixture of a mono-olefin copolymer rubber, NBR and a polyolefin plastic, thereby effecting the partial co-crosslinking of the mixture.
CONSTITUTION: A monoolefin copolymer rubber, an acrylonitrile.butadiene copolymer rubber (NBR) and a polyolefin plastic are mixed and kneaded together. When the polyolefin plastic is molten, a small amount of a crosslinking agent (an organic peroxide) is added and dispersed in the polymer. Upon dispersion, the crosslinking agent reacts nearly completely with the polymer to effect the partial crosslinking of the mono-olefin copolymer rubber with the NBR to obtain the objective composition. The composition may contain a pigment, a heat stabilizer, etc. The NBR is pref. that of low acrylonitrile content (15W35wt%) to improve the affinity with the monoolefin copolymer rubber.
