| 摘 要： | 以马来酸酐(MA)、聚乙二醇(PEG)、烯丙基磺酸钠(SAS)等为原料,通过自由基共聚合成了含柔性链且具有两亲结构的水溶性超分散剂。研究了复合材料的力学性能、热性能、晶型结构和微观结构,探讨了复合材料的界面增容机理。结果表明,当超分散剂的用量为3%(质量分数,下同)时,复合材料的冲击强度达22.09 kJ/m2,比未经超分散剂处理的复合材料提高了40%,材料的结晶度也有所提高,但晶型仍以α-PP为主。

| Abstract: | Super-dispersant containing the flexible chain structure with hydrophilic and hydrophobic groups was synthesized by using maleic anhydride(MA),polyethylene glycol(PEG),sodium allyl sulphonate(SAS),etc as raw materials through radical copolymeriation.The mechanical properties,thermal properties,crystal structure, micro-structure and the mechanism of the interface capacity of composite materials were studied in detail.The results show that when the amount of poly-dispersant up to 3% the impact strength of com... |
