Abstract

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

Claims (4)

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