聚丙烯具有物理机械性能优异,成型加工容易,密度小,耐化学稳定性优良,电绝缘性能优异等优点,广泛用于化工、电器、包装等行业。PP 还可与其它材料填充或共混改性制得满足不同使用要求的材料,但由于其非极性,与极性聚合物和无机填料等的结合力差,导致力学性能降低,很大程度上限制了PP 的应用范围。
为了扩大PP的应用范围，提高PP的综合性能，许多研究人员就PP的改性开展了大量卓有成效的研究工作。对聚烯烃接枝极性单体使其极性化，利用极性基团的极性和反应性，改善其性能上的不足，是扩大高分子材料用途的一种简单而又行之有效的方法。
本实验采用聚丙烯接枝丙烯酸单体，为改善非极性PP与极性高聚物及无机填料的相容性差的状况，作为增溶剂使用。
结果表明，在微波加热时间为111分钟，AA用量为PP用量的25%，熔胀时间为150分钟，熔胀温度为100时0C，BPO用量为PP用量的1%的最佳反应条件下，接枝率达12%。微波时间、引发剂、界面剂、接枝单体等因素对丙烯酸固相接枝PP反应的影响较为相似，均为随着用量增加，接枝率呈先升后降（或平稳）变化趋势。

PP材料的介绍
PP has excellent mechanical properties, forming easy, density, chemical resistance stability and good electrical insulation outstanding performance advantages, widely used in chemical engineering, electrical appliances, packaging and other industries. PP can also be filled with other materials or blends in the modified system to meet the requirements of the use of different materials, but because of its non-polar and polar polymers and inorganic filler, such as the integration of the poor, resulting in lower mechanical properties, to a large extent PP limit the scope of application.
In order to expand the application of the PP, PP improve the comprehensive performance, many researchers modified the PP in a lot of fruitful work. Polarity of the polyolefin graft monomer to polarity, the use of polar groups polarity and response, improve its performance on the lack of polymer materials to expand the use of a simple and effective Methods.
