| 摘 要： | 引言 在同一分子中,既含有亲水性链段,又含有疏水性链段的聚合物称为两亲性聚合物,这种聚合物的凝聚态常具有多相结构,并对不同极性的化合物都具有一定的亲和力,这种独特的性质就使其既不同于低分子表面活性剂也异于一般的离子聚合物.带有亲水性支链的两亲性聚合物具有很大的应用潜能.可以用作乳液和分散体的稳定剂,颜料及塑料的表面改性剂,高分子材料的助剂及改性剂等[1-2].

| Abstract: | A hyperbranched poly(ester-amide)(HP) with hydroxyl end-groups was synthesized from diisopropanolamine (DIPA) cis-1,2-clyclohexane-dicarboxylic anhydride (HHPA) and pentaerythritol (PETL), and a kind of amphiphilic hyperbranched macromolecule was prepared with the hydroxyl end-groups modified by the addition of polyethylene glycol monomethyl ether（MW550, MPEG550）.The structure of the macromolecules was characterized with IR, DSC, GPC and SEM.The results indicated that the hyperbranched poly(ester-amide) had narrow molecular mass distribution with polydispersity 1.47, and glass transformation temperature (Tg) 36℃.It was shown by SEM micrographs that the amphiphilic polymer in water solution exhibited nano-spherical particles dispersion with 50～100 nm diameter. |
