摘　　要：综述了高熔体强度聚丙烯的几种制备方法,如射线辐照法、过氧化物反应挤出法、大分子单体共聚法和反应性聚烯烃中间体法等。同时还介绍了高熔体强度聚丙烯在挤出发泡、热成型、挤出涂布以及吹塑薄膜等领域的应用情况。This paper reviewed some approaches in the preparation of high melt strength polypropylene, including electron beam irradiation, peroxides reactive extrusion, macro monomer copolymerization, as well as reactive polyolefins intermediate. HMSPP is a research hot spot in polypropylene field. Design and synthesis of HMSPP with well-controlled molecular will be the main stream of the research on HMSPP. The potential uses of high melt strength polypropylene in the field of extrusion foaming, thermoforming, extrusion coating and blown film were also introduced.
