Prepolymer formation |
| abstract |
ABSTRACT A process and urethane composition for making urethane pre-polymers from a polyisocyanate and blends of two or more urethane intermediates. The prepolymers so produced when cured have improved physical properties such as high low strain modulus and tensile strength relative to cured polyurethanes prepared from a mixture of prepolymers prepared by reacting a polyisocyanate with the component intermediates and subsequently blending the prepolymers. |
