| 摘 要： | 采用溶液聚合法制备了苯乙烯-马来酸酐共聚物（SMA），研究了反应时间、引发剂浓度、单体浓度对产率的影响；用二元胺（己二胺和乙二胺）对SMA进行了扩链研究，红外光谱证实发生了扩链反应，热重分析表明扩链产物的热稳定性提高，并且随二元胺链长的增大热分解温度提高．

| Abstract: | Styrene-maleic anhydride copolymer(SMA) was synthesized by solution polymerization,the effect of reaction time,initiator concentration and monomer concentration on the yield of SMA were investigated.The reaction of SMA with Hexamethylene diamine(HMDA) and ethylenediamine(EDA) was carried out.The resulting chain-extended SMA was confirmed by FTIR analysis.The TGA results showed that the decomposition temperature of chain-extended SMA was higher than that of unmodfied SMA and increased with chain lengh of diamine for the chain extension reaction of SMA with diamine. |
