不同成核作用硅灰石混杂填充PP复合材料性能研究
β-PP复合材料的力学性能优于a-PP复合材料，尤其冲击强度[1-2]，其结晶性能和力学性能已有大量研究[3]，但具有不同成核机理无机填料混杂填充PP复合材料的研究鲜见报道。本文采用具有β-成核作用的硅灰石(WIoo)和具有α-成核作用的硅灰石(W)混杂制备填充PP复合材料，研究了不同成核机理硅灰石之间的竞争作用和混杂填充PP复合材料的结晶和力学性能。

纳米管对|3一成核PP的结晶行为与熔融特性的影响
已有大量研究表明碳纳米管( CNT)填充聚丙烯(PP)主要形成α-晶[1]，己知β-晶PP比α-晶具有高的韧性，但CNT填充β-PP复合材料研究报道不多 。本文选用TMBs、庚二酸钙(CaPA)及纳米碳酸钙负载庚二酸钙NA200作为β一成核剂，制备了多壁碳纳米管(MWCNT)填充β一成核PP复合材料，研究了不同β一成核剂在填充PP复合材料中的β一成核能力和晶型变化规律，考察了MWCNT用量、不同p一成核剂及用量对p一成核能力和p一晶含量的影响，探讨了...

polypropylene blends with poly (styrene-b-(ethylene-co-butylene)-b-styrene) under irradiation: A comparative investigation
关键字：Electron beam irradiation, Poly (styrene-b-(ethylene-co-butylene)-b-styrene) (SEBS), Polypropylene (PP), Crystallinity, Molecular weight
The aim of this paper is to investigate the stabilization of polypropylene in the poly (styrene-b-(ethyleneco-butylene)-b-styrene) (SEBS)/polypropylene (PP) blends under irradiation with respect to PP. The PP films, SEBS/PP films were subjected to electron beam irradiation and characterized by wide angle X-raydiffraction (WAXD), differential scanning calorimetry (DSC), gel permeation chromato...

增容PP/回收PET共混物的动态流变行为
关键字：增容,回收,PET,混物,动态,流变,
本工作用双螺杆挤出机制备了未增容与增容的PP/回收PET（r-PET）共混物，所用相容剂为聚丙烯接枝马来酸酐（PP-g-MA）和聚丙烯接枝甲基丙烯酸缩水甘油酯（PP-g-GMA），高级旋转流变仪研究了共混物在260℃时的动态流变行为。研究结果表明，增容与未增容共混物的动态储能模量（G’）都随着扫描频率（ω）先减小后增大，即在低频处出现“第二平台”，认为这与r-PET粒子的形变驰豫和体系内部形成网络结构有关，此外，PP-g-MA对PP/r-PET共...
