聚烯烃通过接枝改性可以有效地扩大其应用范围。本文简介了近几年反应挤出中聚烯烃接枝体系的组成和接枝机理,讨论了影响因素及其存在的副反应,同时介绍了接枝产物在增容改性等方面的应用。
Modification of polyoletin by melt grafting is an effective way to expand the application of the polyolefin. In this paper, the composition and mechanisms of grafting by reactive extrusion in recent years are briefly introduced, and the influences of different factors as well as side reactions are discussed. Meanwhile, the application of the grafted polyolefin in the compatibilization is also introduced.
