    摘要: The present invention relates to polyurethane, and specifically relates to a polyurethane microcellular elastomer, a method for preparing the same, and the use thereof. The polyurethane microcellular elastomer is the reaction product of (1) an isocyanate-terminated prepolymer obtained by reacting an isocyanate with a first polyol, (2) a second polyol, (3) a chain extender and (4) a catalyst, wherein the first polyol and/or second polyol comprise at least one polycarbonate polyol obtained by reacting carbon dioxide with an alkene oxide. This method of preparing polyurethane microcellular elastomer can not only reduce the demand for raw materials derived from petrochemicals, but also realize the utilization of the “greenhouse gas” carbon dioxide.
