摘要
本文研究聚氯乙烯(PVC)与端-2-噁唑啉聚环氧丙烷(活性聚醚)在加工过程中的接枝反应,通过溶剂萃取、IR、DSC、GPC和SEM分析方法证实接枝反应的发生,并发现无催化剂存在时,在PVC加工温度下亦能较快的发生接枝共聚反应。
The mechanical graft copolymerization of PVC with the 2-oxazoline-terminated poly (propylene oxide) by heating process of the bulk polymers has been studied. The occurrence of graft reaction was verified by solvent extract, IR, GPC, DSC and SEM analysis. It was found that the graft eopolymerization of PVC with reactive polyether could take place in absence of any catalysts under certain temperature.
