摘要:以靛红酸酐(IA)与聚乙二醇单甲醚 550(MPEG550)合成带有伯氨基的活性支链(IP550),并对苯乙
烯-马来酸酐共聚物(SMA)进行酰胺化改性,制备出梳状改性 SMA(SMA-IP550)。考察了产物的合成条件,

并采用 FTIR 和 HNMR 对 SMA-IP550 的结构进行表征。结果表明:催化剂(4-二甲氨基吡啶)用量为反应物
总质量的 0.9%,MPEG550 和 IA 的物质的量比为 1∶1,反应温度 120 ℃,反应时间 30 min,活性支链 IP550 产
率达 79.3%;SMA 改性温度为 140 ℃,IP550 与 SMA 中马来酸酐(MA)的物质的量比为 0.5∶1,反应体系的固含
量 30%,反应时间 2 h,得到接枝率为 42.5%的改性苯乙烯-马来酸酐共聚物(SMA-IP550)。通过对比不同长度
活性支链改性 SMA 的分散、降黏、乳化和润湿性能,结果表明该类助剂结构可调,其分散作用以及乳化作用与
结构紧密相关。

Abstract: An active branched chain (IP550) with a primary amino group was synthesized by isatoic
anhydride (IA) and methoxypolyethylene glycols 550 (MPEG550). An amidation reaction between
styrene-maleic anhydride copolymer (SMA) and IP550 led to comb-like modified polymer surfactant
(SMA-IP550). The synthesis conditions of IP550 and SMA-IP550 were investigated. The chemical
1
structure of SMA-IP550 was characterized by FTIR and HNMR. The results showed that when dosage of
catalyst (4-dimethylaminopyridine) was 0.9% of the total mass of reactants, molar ratio of MPEG550 to IA
was 1∶1, reaction temperature was 120 ℃, and reaction time was 30 min, the yield of IP550 reached
79.3%. Modified SMA(SMA-IP550) with 42.5% grafting yield was obtained under the conditions of
temperature 140 ℃, molar ratio of IP550 to MA 0.5∶1, solid content 30%, and reaction time 2 h. By
comparing the dispersion, viscosity reduction, emulsification and wettability of modified SMA with
different branched-chain lengths, it was found that the structure of comb-like modified styrene-maleic
anhydride copolymer could be adjusted, and their dispersion and emulsification were closely related to their
structure.
