    摘要: This invention relates to solid elastomers which exhibit reduced dimensional shrinkage, and to a process for the production of these elastomers. These elastomers comprise the reaction product of a polyisocyanate component or prepolymer, with an isocyanate-reactive component comprising a high molecular weight component having an EO cap having less than 17% by wt., a chain extender and optionally, a crosslinker, in the presence of at least one catalysts. These solid elastomers are produced via the reaction injection molding process in a closed mold, preferably at an isocyanate index of about 70 to about 130.
