摘要
以AIBN为引发剂 ,采用溶液聚合法合成了苯乙烯—马来酸酐交替共聚物 (SMA) ,并使其在溶液中与液化MDI进行接枝聚合。用IR ,DSC ,TG等对接枝聚合物给予了表征。结果表明 ,SMA与液化MDI之间进行了接枝聚合 ,接枝聚合物有一玻璃化转变温度Tg。
Alternating copolymer of styrene-maleic anhydride (SMA) was synthesized by solution polymerization, using AIBN as initiator, and graft-copolymerized with liquidated-MDI. SMA and graft-copolymer were characterized by IR, DSC and TG, and the results were discussed. The results showed that the graft-polymerization between SMA and liquidated-MDI had done,the graft-polymer had a glass-transition temperature (Tg), 102℃, and the thermal stability of the graft-polymer was higher than the product which was directly synthesized by MA and liquided-MDI.
