                 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,
                              1
                 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

                 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.
