Abstract

Abstract: Polyolefins modification by reactive extrusion with itaconic acid and derivatives can improve the performance of polymers, especially for its compatibility with other polymers. From the point of factors that impact graft reaction of polyolefins i.e. type of polyolefin, initiators and additives, the progress both at home and abroad was summarized. Modification mechanisms and structure of graft products were emphasized. Some problems and feasible research areas in this field, for example, the chain structure of graft products and the effect of screw profile on reactive extrusion, were worth further research.

Key words: itaconic acid, polyolefins, reactive extrusion, polymer processing

摘要： 通过反应挤出的方式, 采用衣康酸及其衍生物对聚烯烃进行接枝改性, 可以显著改善材料性能, 特别是与其他高分子材料的相容性。本文从影响聚烯烃接枝改性的各个因素:聚烯烃类型、引发剂类型以及添加剂出发, 详细论述了国内外研究者的研究进展, 重点阐述了各个因素对聚烯烃改性机理、产物链结构的影响, 认为反应挤出接枝产物链段结构以及螺杆结构对反应挤出的影响这两方面值得进一步研究。
