【摘要】 以双螺杆挤出机为反应器 ,在自由基引发剂过氧化二异丙苯 (DCP)存在下 ,加入添加剂 ,采用熔融法对线型低密度聚乙烯 (LLDPE)进行马来酸酐 (MAH)接枝 ,对产物的接枝率 (Gx)、凝胶含量 (gel)以及溶体流动速率(MFR)的影响因素进行了系统的研究 ,并测试了接枝共聚物与铝片的粘接强度更多还原

【Abstract】 This article dealed with the linear low density polyethylene(LLDPE)melt grafted by maleic anhydride(MAH) in a twin screw extruder with radical initiator DCP and some additives and studied the influences on the grafting rate(Gx),gel fraction of crosslinked product(gel) and melt flow rate(MFR).In addition,the adhesive strength of the graft copolymer to aluminium was tested.更多还原
