| 摘 要： | 本文采用反应型双螺杆挤出机和熔融接枝技术制备了可反应性相容剂HDPE-g-ITA和HDPE-g-(ITA co-St),借助气相色谱和热重分析技术,确定了熔融接枝工艺和工艺参数。应用红外光谱分析了接枝物的化学结构,证明熔融接枝过程中部分羧基脱水生成酸酐；接枝率和熔体流动速率测定结果表明,衣康酸(ITA)的接枝能力较马来酸酐(MAH)强,引入第二单体苯乙烯(St)对提高ITA的接枝率有更大的促进作用。 |

| Abstract: | The reactive eompatibilizers,HDPE-g-ITA and HDPE-g-(ITA-co-St),were prepared by melt grafting technique through reactive twin screw extrusion.The melt grafting process and process parameter were assured through GC and TG analysis.The chemical structure of the grafted polymers were analyzed by FT-IR.Some carboxyl was changed into anhydride with losing water during the melt grafting process.The results of graft ratio and melt flow ratio indicated that the ability of ITA grafting with HDPE is higher than MAH.St,the second monomer,have large promoter action for the graft ratio of HDPE grafting ITA than MAH. |
