The result shows that for both PCL homopolymers and PCL-b-PEG block copolymers, the spherulitic linear growth rate first increases with molecular weight and reaches a maximum, then decreases as molecular weight increases. Crystallization temperature has greater influence on the spherulitic growth rate of polymers with higher molecular weight.

当自由PEG在水中的占有面积S_o与单根PEG链段所占有的表面积S的比值S_o／S的值接近或小于3时，PEG链段对胶束形状的影响较小，PCL嵌段的影响占主导地位，易形成片状胶束；当S_o／S的值在3-10之间时，随着PCL嵌段分子量的增加，PCL-b-PEG嵌段共聚物在水溶液中自组装形成类似球状、棒状和蠕虫状胶束，是PEG与PCL嵌段共同的作用的结果；当S_o／S的值大于10时，易形成球状胶束。
