| 摘 要： | 在最新实验结果的基础上论述了一种在聚合物反应性共混过程中的相态控制新方法－－共聚物分子的界面拔出。通过选择组分高聚物的种类和调节反应性高分子共混物两相相对组成，可控制在两相界面上原位生成共聚物分子的构造，从而可系统分析分子构造与界面提出之间的关系；通过改变熔融共混剪切速率或共混物的熔体粘度，评述了外界流场的作用强度对共聚物分子的界面提出的影响。

| Abstract: | A new approach of morphology control during reactive blending of immiscible polymers--pull-out of copolymers was reviewed on the basis of latest experimental results. By selecting of the species of component polymers and adjusting the composition of reactive blend, the architecture of in situ-formed copolymers at the interface of two phase could be manipulated. The effect of the molecular architecture on the pull-out of the interface was then systematically analyzed. Also, the influence of the magnitude of external forces on the pull-out of copolymers was evaluated by varying shear rate or melt viscosity during melt mixing. |
