Abstract

The present invention is a blend of a polymeric hydrocarbon and a thermoplastic polyurethane which is compatibilized a polymeric hydrocarbon that contains low concentrations of isocyanate reactive group. The compatibilizer can be prepared by reacting a modified polymer having pendant or incorporated amine-reactive groups with a hydroxyl amine, a diamine, or a polyethermonoamine. The compatibilized blend may further include a non-TPU engineering thermoplastic to form compatible blends of the polymeric hydrocarbon and the non-TPU engineering thermoplastic. In this case, the TPU is used as a co-compatibilizer.
