摘要

2075635 9112286 PCTABS00006 A polyurethane composition for use in RIM processes which composition comprises an MDI-polyol prepolymer, an aromatic diamine chain extender and a "cold break"-reducing additive to prevent "cold break" and to increase the flexural modulus of the polymer, which additive comprises triethanol amine or a triethanol amine-ethylene oxide end cap reaction product.
