摘要
本文研完了氯乙烯-丙烯酸丁酯(VC-BA)共聚物的热降解过程,发现随升温速率升高,降解温度线性升高,而降解率变化不大。降解时首先是BA链节上的醇基消除,并有羰基残存,接着是HCl消除,最后主链断裂。
The thermal degradation process of vinyl chloridebutyl acrylate random copolymer (VC-BA) has been studied by TG and DSC in liner heating rates. It has been found that the thermal degradation temperatures of VC-BA were rised linerly with the raise of the heating rates. When the degradation, at first, the-OC4H9 on BA was eleminated, but the most of-C = O at BA were remained, then HCI was eleminated, at last, the mam-chain was degradated.
