Polyurethane/polyureas

Polyurethane/polyureas

This invention relates to polyurethane/polyureas. These polyurethane/polyurea materials comprise the reaction product of (A) a polyisocyanate prepolymer having an NCO group content of about 4 to about 30% and an average functionality of 1.8 to 6, and (B) an isocyanate-reactive component comprising a...

description This invention relates to polyurethane/polyureas. These polyurethane/polyurea materials comprise the reaction product of (A) a polyisocyanate prepolymer having an NCO group content of about 4 to about 30% and an average functionality of 1.8 to 6, and (B) an isocyanate-reactive component comprising at least one aromatic diamine compound. The (A) polyisocyanate prepolymers herein comprise the reaction product of (1) at least one (cyclo)aliphatic polyisocyanate with (2) an organic compound having 1.8 to 5 hydroxyl groups and a hydroxyl equivalent weight of 150 to 2000 g/eq., and which is selected from the group consisting of OH-functional polybutadienes, OH-functional polyalkylene, OH-functional polyalkylene phthalates, OH-functional polyalkylene isophthalates, OH-functional polyalkylene terephthalates and mixtures thereof.
