Abstract: The present invention is to the preparation and application of isocyanate based polymers, particularly polyurethane and polyurea elastomeric polymers. By incorporating polybutadiene with a polyether polyol in a polyurethane system, the produced elastomer have improved chemical resistance as compared to conventional polyurethane elastomers. For polyurea elastomer, the incorporation of high functional polyols or crosslinkers with polybutadiene gives elastomer with improved chemical resistance as compared to conventional polyurea elastomers.

Abstract: The present invention relates to an isocyanate-terminated prepolymer composition obtained from reaction of a methylene diphenylisocyanate, comprising at least 25 weight percent of the 2,4?- isomer, with a polycaprolactone polyol; and to polyurethane or polyurea elastomers obtained from the said isocyanate-terminated prepolymer composition.
