| 摘 要： | 通过熔融接枝的方法在聚丙烯（PP）分子链上接枝甲基丙烯酸缩水甘油酯（GMA），制得PP接枝物PP-g-GMA，然后采用多个胺基的偶联剂聚六亚甲基胍（PHMG）对其进行偶联反应，制备偶联的聚丙烯（MPP）。通过与通用聚丙烯（EPS）以及进口专用料（PF-814）的对比，考察了经过偶联改性的MPP熔体的流变特性。结果表明：与原料EPS和PF-814相比，改性后MPP熔体的低频剪切区储能模量、挤出胀大、稳态柔量、零剪切黏度及熔体强度等都有明显增大。

| Abstract: | Polypropylene (PP) was grafted with glycidyl methacrylate (GMA) to prepare functional PP (PP-g-GMA) by melt grafting reaction. Then PP-g-GMA was coupled by a coupling agent, polyhexa methylene guanidine (PHMG), which contained two primary amine groups at two ends of the molecule, to prepare a coupled PP (MPP). Compared with the general PP (EPS) and the commercially imported PP (PF-814), the melt rheological properties of the prepared MPP were investigated. Results showed that the storage modulus at low frequency region, the extrusion swell, the steady state compliance, the zero shear viscosity and the melt strength of MPP increased in comparison with EPS and PF-814. |
