Abstract: A series of casting polyurethane (CPU)resins were synthesized by using 4,4′-methylene diphenyl dissocyanate (MDI), polyols, crosslinking agent,special aids, and a number of heat resistant polyurethane resin were prepared by semi-prepolymerization.Their structures were studied with FTIR,the thermal stability of CPU was examined with DSC and TGA.The mechanical property of CPU were measured.The CPU with high thermal stabilities and excellent mechanical properties could be used in the fields of high temperature, high impact strength, etc.
