发明名称 MECHANICALLY COMPATIBLE POLYURETHANE/POLYOLEFIN THERMOPLASTIC POLYMERIC BLENDS
摘要 Polymeric blends of thermoplastic polyurethane elastomers and crystalline or predominately crystalline polyolefin thermoplastics are produced by high shear mixing of melts of the respective polymers. The stabilized mechanically compatible blend of the ordinarily thermodynamically incompatible polymers comprises from about 3.5 to 20 parts by weight of a polyolefin homopolymer or copolymer with 100 parts by weiqht of polyurethane. The mechanically compatible polymeric blend is particularly useful for molding piastic articles by injection molding, extrusion, calendering or similar process for molding thermoplastic articles.
