摘要
以辛基酚聚氧乙烯醚丙烯酸酯(C8PhEO10Ac)为大分子单体,丙烯酸(AA)、丙烯酰胺(AM)为共聚单体,采用大分子单体接枝共聚法,制备了一种两亲性接枝共聚物(AA-AM-g-C8PhEO10Ac),用静态光散射(SLS)与GPC联用技术测得接枝共聚物的分子量为9.51×105,用FTIR、1H NMR和TG/DTA等手段对共聚物的结构及性能进行了表征。采用透射电子显微镜(TEM)对聚合物在水溶液中的自组装行为进行了初步研究。结果表明,AA-AM-g-C8PhEO10Ac在水溶液中自组装,形成球型胶束,随着浓度增大,趋向于形成更大的自组装体。
An amphiphilic graft copolymers （AA-AM-g-C8PhEO10Ac） was prepared by graft cop01ymerization of n-octylphenyl polyoxyethylene acrylate （C8PhEO10Ac） macromonomer, acrylic acid （AA） and acrylamide （AM） in aqueous solution. The molecular weight of the copolymer was determined to be 9.51 x 105 by static light scattering （SLS）. The structures and properties of the graft copolymer were charac- terized by FTIR,^（1）H NMR and TG/DTA. Self-assembly behavior of AA-AM-g-CsPhEOloAc in aqueous so- lution was preliminary studied by transmission electron microscopy （TEM）. The result showed that the mo- leculars of AA-AM-g-Cs PhEO10Ac copolymer form globular micelles in water, with an increase in the con- centration, the copolymer tended to form larger micelle aggregates.
