热塑性聚氨酯共混改性研究进展

综述了热塑性聚氨酯与聚烯烃、聚苯乙烯、工程塑料(聚碳酸酯、ABS、聚甲醛、苯乙烯一丙烯腈共聚物、聚酰亚胺、聚酰胺等)、环氧树脂、橡胶、短纤维、聚氯乙烯树脂等共混研究进展，共混改性后的材料在某些性能上得到提高或改善，共混的研究为开发新材料提供了新途径，扩大了热塑性聚氨酯的应用。

Research Development of Blending Modification of Thermoplastic Polyurethane

The research development of blending modification of therrrmoplastic polyurethane(TPU)with some polymers and additive agents are reviewed. The properties and applications of the blends that cntained thrmoplastic polyurethane and the oplymers,such as polyethylene,polyvinyl cloride,polystyrene,engineering plastics(polycarbonate,acrylonitrile-butadiene-styrene copolymer,polyoxymethylene,styrene-acrylonitrile copolymer,polyimide,polyamide),epoxide resin and rubbers are summarized with 52 references. The blends of thermoplastic polyurethane and some polymers shows that the mechanical properties of these blending materials can be mprowed and the applicatin of thermoplastic polyurethane can also be enlarge.
