Abstract (en)

[origin: WO8504410A1] Improved integral skin microcellular polyether polyurethane elastomer products, e.g., shoe soles, which are characterized by outstanding low temperature dynamic flex and green strength at demold, at specific gravities as low as about 0.4 gm/cc. These elastomer products are desirably prepared from a two-component system, e.g., the reaction of Package A containing improved normally liquid quasi-prepolymers, with Package B comprising a compatible liquid mixture containing polymer/poly(oxyethyleneoxypropylene)polyol, difunctional chain extender, halogenated blowing agent and optionally other ingredients. The said liquid quasi-prepolymers are derived from the reaction of (1) a mixture of normally solid diphenylmethane diisocyanate, carbodiimide and/or uretone imine and (2) poly(oxyethyleneoxypropylene)polyols.
