摘要

由于性价比高，聚丙烯(PP)成为增长最快的通用塑料，在汽车工业、家用电器和管材方面得到了广泛地应用。然而由于聚丙烯自身的非极性限制了其在某些领域的应用，向聚丙烯主链上接枝极性单体是改善其极性的有效方法。常用的接枝改性方法有：溶液接枝、熔融接枝、等离子体处理、表面可控活性聚合以及超临界 CO

状态下接枝等。其中超临界CO

由于溶解单体能力强，对聚合物基体也有很好的溶胀能力，且阻燃性好、无毒以及价格相对低廉，克服了传统接枝方法存在的操作工艺复杂，溶剂不易回收等缺点，得到了广泛研究。本文从超临界CO

协助固相接枝改性机理、接枝单体的选择、影响过程的因素以及超临界CO

协助固相接枝的应用等方面出发，系统阐述了超临界CO

协助PP固相接枝改性近些年来的研究概况。

Abstract

Polypropylene has become one of the most widely used and rapidly growing general plastics

but its application is restricted in some areas owning to its non-polarity. Grafting polar monomers to the PP main chain is one of the most effective methods to improve its polarity. There are several common methods

such as high-energy radiation grafting

UV-induced surface grafting

plasma

controlled/living polymerization

supercritical CO

assisted grafting etc. Among these methods

supercritical CO

assisted grafting has been widely applied because of its good solubility to monomers

good swelling ability to polymer matrix

non-toxic

non-flammable

and relatively low cost. In this paper

advances in supercritical CO

assisted grafting of polypropylene in solid phase were systematically reviewed in several aspects

such as grafting mechanism

selection of monomers

impact factors and application of supercritical CO

assisted grafting of polypropylene.
