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.

Claims (4)

1. A material comprising the reactive product of an A-side comprising a prepolymer diisocyanate and a B-side comprising a first blown vegetable oil, a cross-linking agent comprised of a multi-functional alcohol and a catalyst, wherein the first blown vegetable oil and the cross-linking agent are substantially non-esterified prior to the A-side reacting with the B-side.

2. A method of preparing a material comprising the steps of combining an A-side material comprising a prepolymer diisocyanate with a B-side comprising a first blown vegetable oil, a cross-linking agent comprised of a multi-functional alcohol and a catalyst, wherein the first blown vegetable oil and the cross-linking agent are substantially non-esterified prior to combining the A-side with the B-side.

3. A material comprising the reactive product of an A-side comprising a prepolymer isocyanate and a B-side comprising a first blown vegetable oil, a cross-linking agent comprised of a multi-functional alcohol and a catalyst, wherein the first blown vegetable oil and the cross-linking agent are substantially non-esterified prior to the A-side reacting with the B-side.

4. A method of preparing a material comprising the steps of combining an A-side material comprising with a B-side material, wherein said A-side comprises a prepolymer isocyanate and a B-side wherein the B-side comprises a first blown vegetable oil, a cross-linking agent comprised of a multi-functional alcohol, a catalyst, and a blowing agent, wherein the first blown vegetable oil and the cross-linking agent are substantially non-esterified prior to combining the A-side with the B-side.
