摘　　要：介绍了烯基双酚Ａ醚（ＤＢＡＥ）在引发剂过氧化二异丙苯（ＤＣＰ）存在下，与低密度聚乙烯（ＬＤＰＥ）在Ｈａａｋｅ转矩流变仪的混炼器中进行熔融接枝反应的工艺。采用示差扫描量热仪（ＤＳＣ）、红外光谱（ＦＴ－ＩＲ）分析了接枝共聚反应和证实了接枝共聚物ＬＤＰＥ－ｇ－ＤＢＡＥ的结构。并通过正交实验及数据分析，确定了合成ＬＤＰＥ－ｇ－ＤＢＡＥ的最佳工艺条件。his paper introduced the melting graft reaction of low density polyethylene (LDPE) and diallyl bisphenol A ether (DBAE) using dicumyl peroxide (DCP) as initiator in the mixer of Haake rheometer. The copolymerization reaction was confirmed by DSC through which the initial, peak and end temperatures of reaction under static state were obtained. The graft product named as LDPEgDBAE was characterized by IR. Orthogonaldesigning results show that the optimal conditions for LDPEgDBAE composition are DCP 0.5 mass%, DBAE 8 mass% and temperature 190 ℃, the order of notability affecting on GR is the content of the DCP, DBAE and temperature.
