摘要

聚丙烯(PP)是一种具有优异性能且价格低廉的通用高分子材料

但由于聚丙烯为非极性聚合物

其染色性、亲水性、粘结性等均较差

且与其它材料的相容性也很差

这些缺点限制了聚丙烯的应用。通过固相接枝法改性聚丙烯

不仅可以在保持聚丙烯原有优异性能的情况下引入极性官能团

而且具有低温、低压、低成本、较高的接枝率和无需溶剂回收等优点。本文简要介绍了PP固相接枝反应机理

从接枝单体角度综述了近几年PP固相接枝改性的研究进展

并讨论了反应工艺对接枝产物的接枝率、接枝效率和性能的影响。

Abstract

Polypropylene (PP) is a general polymer material with excellent performance and low price. However

the use of PP has been restricted by its poor dyeability

hydrophilicity

cohesiveness

and poor compatibility with other materials because of the nonpolarity of PP. Introduction of polar functional group to molecular chain of polypropylene (PP) by the method of solid phase grafting copolymerization would not only keep the original excellent properties of PP

but also have the advantages of low temperature

low pressure

low cost

high grafting degree and no need of solvent recovery

etc. In this paper

the reaction mechanism of solid-phase grafting was briefly introduced

and the latest advances in solid phase grafting copolymerization of polypropylene from the aspect of grafting monomers were reviewed. The effect of the reaction technology on grafting degree

grafting efficiency and properties of grafting copolymer was then discussed.
