摘要

本研究采用马来酸酐（ＭＡ）对线型低密聚乙稀（ＬＬＤＰＥ）作改性处理，并找出用于木纤维－塑料复合材料的聚乙稀－马来醚酐共聚物的适宜制备工艺条件。研究结果表明，在自由基引发条件下，ＬＬＤＰＥ－ＭＡ共聚物的形成是可行的。红外光谱及接枝率测定显示了在非极性的ＬＬＤＰＥ分子中极性基团的存在。通过改变工艺多数，ＭＡ对ＬＬＤＰＥ的接枝率有较大提高。极性共聚物对木纤维－塑料复合材料的制备具有现实意义。

Abstract

Modification of linear low density polyethlene(LLDPE ) with maleic anhydride(MA)was studied and suitable conditions for LLDPE-MA copolymer preparation in the manufacture ofwood fiber-plastic composites were found.The test data of infrared spectra(IR)and graft-rate de-termination showed the existence of polar groups in the non-polar LLDPE-MA molecule. The results also showed the formation of LLDPE-MA copolymer can be obtained by free group initiationand the extent of reaction of MA to LLDPE can be improved by changing process conditions. Thecopolymer obtained in this study would be very useful for making wood fiber-plastic composite.
