    摘要: A curable thermoplastic elastomeric composition comprising: (a) polytrimethylene ether ester elastomer; (b) crosslinkable poly(meth)acrylate rubber; and (c) a crosslinking system to crosslink the rubber. A melt processible thermoplastic elastomeric composition comprising: (a) a continuous phase comprising polytrimethylene ether ester elastomer; and (b) crosslinked poly(meth)acrylate rubber disperse phase. A process for manufacturing a melt processible thermoplastic elastomeric composition comprising the steps: (a) providing a cross-linkable poly(meth)acrylate rubber; (b) providing crosslinking system in an amount effective to crosslink the poly(meth)acrylate rubber; (c) providing polytrimethylene ether ester elastomer; (d) forming a mixture of the cross-linkable poly(meth)acrylate rubber, the polytrimethylene ether ester elastomer and the crosslinking system; (e) cross-linking the cross-linkable poly(meth)acrylate rubber in the mixture using the crosslinking system; and (f) recovering a melt processible thermoplastic elastomeric composition comprising the polyether ester elastomer as a continuous phase and the crosslinked poly(meth)acrylate rubber as a disperse phase. A shaped article (e.g., an extruded or molded article) made from a melt processible thermoplastic elastomeric composition comprising: (a) a continuous phase comprising polytrimethylene ether ester elastomer, and (b) a disperse phase comprising cross-linked poly(meth)acrylate rubber. Preferably the shaped article is selected from the group consisting of hoses, gaskets, films, belts, cable jackets, seals, gears and bearings.
