摘　　要：高熔体强度聚丙烯具有优异的物理机械性能,其发泡制品拥有广泛的用途。文章综述了制备高熔体强度聚丙烯的制备方法,主要有直接聚合法、辐射接枝交联法、硅烷接枝交联法等。硅烷接枝交联法成本适中、产品质量优异,是目前最有希望的改性技术。综述了发泡高熔体强度聚丙烯材料的应用。High melt strength PP （HMSPP） had excellent physical and mechanical properties and its foamed products had wide applications. The producing methods of HMSPP were discussed, including direct polymerization, radiation grafting and cross-linking, silane grafting and cross-linking, and so on. Silame grafting and cross-linking method was the most promising modification method for its medium cost and products with excellent properties. The applications of foamed HMSPP were also reviewed.
