The sizes of the self-assembly micelles of the amphiphilic block copolymers and the effects werestudied by dynamic light scattering and UV-visible spectrophotometer. The micelle sizes werelargely influenced bythe hydrophobic chain content in the copolymer, the properties of the solvent and the copolymer concentration in the organic phase. The morphology of the micelles was investigated by transmission electron microscopy. Theresults showed that the micelles appeared spheres with inner core and outer shell. The critical association concentrations were determined by pyrene monomer fluorescence probe technology. The degradability of copolymer was studied by the loss of the intrinsic viscosity in the degradation process. The results indicated that the degradation rate of PECL was slower thanthat of PELLA and PEDLLA. The stability of the copolymer micelle dispersion was examined by measuring the critical flocculation concentration, which gradually decreased with increasing the content of thehydrophobic chain in the copolymer. The rheological results showed thatthe viscosity ofthe micelle dispersion with higher content of PEG segments was firstly decreased and then increased with the increasingthe temperature. Otherwise, the variation of viscosity was irregular. The viscosity of the micelle dispersion increased with the increase of the electrolyte (Na 2SO 4) concentrations. Polymer micelles paclitaxel was prepared by self-emulsification/solvent evaporation method and solid dispersion technique with amphiphilic block polymers as the carrier material.

运用动态光散射和紫外分光光度计研究了两亲性嵌段共聚物自组装胶束的粒径及其影响因素，结果表明，自组装胶束的形成机理受制备方式的控制，胶束的粒径随着共聚物相对分子质量或疏水嵌段相对分子质量和有机相中共聚物浓度的增大而增大，随着有机溶剂的水溶性的增强而减小；采用透射电镜观察胶束的形态结构，发现胶束呈具有核壳结构的均匀球形；采用芘荧光探针法测两亲性嵌段共聚物的临界聚集浓度；通过降解过程中共聚物特性粘度的变化研究两亲性共聚物的降解性能，发现与PELLA和PEDLLA的相比，PECL 降解速率较慢；随着共聚物中疏水嵌段含量的增大，纳米分散液的稳定性逐渐下降；PEG含量高的PEDLLA纳米分散液随着温度的升高，纳米分散液的粘度先下降然后增大，反之，没有规律性，且随着电解质Na 2SO 4浓度的增大，体系粘度增大。
