| 摘 要： | 以马来酸酐(MAH)为单体、苯乙烯(St)为共单体、过氧化二异丙苯(DCP)为引发剂,采用溶剂热法分别制备了苯乙烯-丙烯腈共聚物(AS)接枝物AS-g-MAH以及AS-g-(MAH-St).利用红外光谱对接枝物进行了结构表征,证明MAH已经成功接枝在AS链上.并用反式滴定法测定了接枝率,讨论了引发剂用量、马来酸酐用量、反应温度、反应时间、反应物浓度和共单体用量对接枝率的影响.结果表明:随着引发剂用量的增加和反应时间的延长,接枝率先增大,然后趋于平稳;随着马来酸酐用量、反应温度和反应物浓度的增加,接枝率先增大后下降;共单体苯乙烯的加入对接枝率的提高有很大的促进作用.

| Abstract: | The grafting copolymer of AS and(AS-g-MAH)and(AS-g-(MAH-co-St))was prepared through solvent thermal process with MAH as monomer,St as comonomer and DCP as initiator.IR spectra confirmed that MAH was successfully grafted onto the AS chain.The grafting degree was determined by a back titration procedure.The influences,such as initiator concentration,MAH concentration,reaction temperature and time,AS concentration,and comonomer concentration on the grafting copolymerization were also studied.The result indicat... |
