摘要
普通聚丙烯(PP)由于熔体强度低和加工温度范围窄,在热成型、挤出涂布和挤出发泡等领域的应用受到限制。高熔体强度聚丙烯(HMSPP)具有较高的熔体强度,使聚丙烯可以在通用设备上熔相热成型、挤出发泡、挤出涂布,从而拓宽了PP应用领域。综述了国内外高熔体强度聚丙烯的研究进展和应用现状。
Ordinary polypropylene （PP） due to the low melt strength and narrow processing temperature range limited itself in the heat molding, extrusion coating and extrusion foam, and other areas of application.High melt strength polypropylene has a high melt strength, so that the PP could be processed in common with hot melt equipment on the molding, extrusion foam, extrusion coating, thus widening the PP applications.This paper reviews the domestic and international high melt strength polypropylene （HMSPP） on the domain of its progress and application.
