| 摘 要： | 通过低密度聚乙烯熔融挤出接枝MAH(马来酸酐)研究了单体及复配单体、引发剂及复配引发剂对LDPE接枝的影响,并用红外光谱法证实了接枝反应。研究表明:复配单体和复配引发剂用量对接枝率有较大影响,AA(丙烯酸)的加入提高了接枝率,DCP/BPO为3/1时接枝率最高。在聚乙烯防雾膜中加入PE g MAH接枝共聚物可提高膜的防雾性。

| Abstract: | Graft copolymerization of low density polyethylene (PE) with maleic anhydride (MAH) was studied by using a Brabender plasticorder.It was proved that the amounts of monomer,compounding monomers,initiator and compounding initiator had large effects on the degree of grafting (D.G.);The introduction of AA increased D.G.;Efficiency of grafting was the best when the ratio of DCP to BPO was third to one. |
