| 摘 要： | 分别采用均相聚合及非均相沉淀聚合法,制备了苯乙烯马来酸酐共聚物(SMA)。考察了引发剂种类和浓度、单体摩尔比、反应温度和反应时间等因素对SMA中马来酸酐(MA)摩尔分数的影响。优化的反应条件为:采用非均相聚合法,以过氧化二苯甲酰(BPO)为引发剂,聚合时间8 h,温度80℃,引发剂浓度0.01 mol/L,单体摩尔比n(St)∶n(MA)=1∶1.5,在该条件下,所合成SMA中马来酸酐的摩尔分数为37.43%,黏均相对分子质量约为89 000,交替性好。将得到的SMA与聚乙二醇单甲醚(MPEG)进行接枝反应,可以制得临界胶束质量浓度为1.03 g/L、表面张力为35.29 mN/m的梳型表面活性剂(SMA-g-MPEG)。

| Abstract: | Due to its special structures,comb-shaped surfactants have the advantage in the use of dispersion stabilizer,interface modifier and biopharmacy application etc.Much attention has been paid to the preparation and application of comb-shaped surfactants.Poly(styrene-co-maleic anhydride)(SMA) with high x(MA) has been prepared to get the comb-shaped surfactant by grafting poly(ethylene glycol)monomethyl ethers(MPEG) onto SMA.SMA was prepared by homogeneous and heterogeneous radical copolymerization.The effects o... |
