ABSTRACT:
A material comprising the reaction product of an A-side having a prepolymer isocyanate, preferably a prepolymer diisocyanate and a B-side having a cross-linker comprising a multifunction alcohol, a first vegetable oil, preferably a blown/oxidized vegetable oil, most preferably a blown/oxidized soybean oil, and a catalyst, wherein the first vegetable oil and the cross-linking agent are substantially non-esterfied prior to combining the A-side with the B-side and the method of producing the same.
