9,9′-双氧杂蒽二醇控制丙烯腈与苯乙烯共聚合的研究

Copolymerization of acrylonitrile and styrene controlled by cycloketyl

采用9,9′-双氧杂蒽二醇(Bixan)引发丙烯腈与苯乙烯共聚,在苯甲醚溶液中聚合时,分子量增长,分子量分布指数为1.4～1.7。用元素分析法测得共聚物的组成,并用差示扫描量热仪(DSC)法测其玻璃化温度,结果表明其为丙烯腈和苯乙烯的无规共聚物。

9,9′-bixanthene-9,9′-diol(Bixan)was used to initiate copolymerization of acrylonitrile and styrene,molecular weight of PSAN was increased with the conversion,and polydispersity was ranged from 1.4 to 1.7 in anisole.Element analysis method was used to measure the composition of copolymer,while glass transition temperature(Tg)was obtained by differential scanning calorimetry(DSC),which provided the evidence that it was a random copolymer of acrylonitrile and styrene.
