Abstract:
An elastomer composition, comprising:(A) at least one elastomer,(B) a plasticizer comprising at least one polymeric material having a weight average molecular weight, M.sub.w, of 500 to 1,000,000, and(C) a curing agent;wherein the at least one polymeric material is substantially permanent within the elastomer; andwherein the at least one polymeric material consists of:(i) at least one monormer unit selected from the group consisting of (meth)acrylic acid; C.sub.10 -C.sub.50 alkyl (meth)acrylates; and C.sub.1 -C.sub.50 alkyl (meth)acrylates substituted with a halogen, a nitro group, a cyano group, a haloalkyl group, a carboxy group, an amino group, an alkylamino group or a dialkylamino group; and(ii) optionally, at least one monomer unit selected from the group consisting of vinylaromatic monomers; vinylaromatic monomers substituted with a halogen, a nitro group, a cyano group, alkoxy group, a haloalkyl group, carbalkoxy group, a carboxy group, an amino group, an alkylamino group or a dialkylamino group; nitrogen-containing ring compounds and thio analogs thereof; nitrogen-containing ring compounds and thio analogs thereof substituted with a C.sub.1 -C.sub.8 alkyl group; vinyl acetate; vinyl chloride; vinyl fluoride; vinyl bromide; vinylidene chloride; vinylidene fluoride; vinylidenebromide;(meth)acrylonitrile; (meth)acrylamide; and dialkylaminoC.sub.2 -C.sub.6 alkyl(meth)acrylamindes.
