    摘要： An elastomer composition, resistant to hydrocarbon fluid and water absorption, comprisinga) an isocyanate reactive component comprising a polypropylene ether polyol containing from about 5 percent to about 60 percent of a dispersion comprising a condensation or addition polymer,b) from about 5 percent to about 35 percent of an epoxy resin, andc) a polyurethane formed from said polypropylene ether polyol, having active hydrogen atoms and at least one isocyanate component in the presence of said dispersion and said epoxy resin,said polyurethane having an isocyanate index of less than 100, said elastomer composition exhibiting less than about 20 percent weight gain after being immersed in kerosene for 24 hours at 38.degree. C.
