摘要

聚合物/聚合物界面的分子链扩散问题在塑料注塑、焊接、共混等领域普遍存在.动态流变法是研究聚合物/聚合物界面分子链扩散的一种有力手段

这种方法对于界面间分子链扩散的监测非常灵敏.本文简述了用动态流变法研究聚合物/聚合物界面扩散的原理、实验方法以及优点

着重讨论了采用该方法研究初始界面分子链末端分布对扩散机理的影响、对称聚合物/聚合物界面分子链扩散的量化

非对称聚合物/聚合物界面的相互扩散

分子量多分散性对聚合物/聚合物界面扩散的影响

聚合物/聚合物界面间的流动和扩散耦合以及近年来动态流变法在化学反应型聚合物/聚合物界面的应用进展.

Abstract

Chain diffusion is widely existed in the injection molding

welding

and blending of polymer materials.Dynamic rheological technique has been proved to be a very sensitive method for studying the chain diffusion at the polymer/polymer interface.This paper gives a brief introduction of the principle and methodology of dynamic rheological technique and its application on the study of polymer/polymer chain diffusion.Influence of the initial chain-end distribution at the surface before contact on the diffusion mechanism

numberization of asymmetric polymer/polymer interface

mutual diffusion of asymmetric polymer/polymer

effect of molecular weight polydispersity on diffusion at polymer/polymer interface

coupling between flow and diffusion at polymer/polymer interfaces

as well as rheological study on interdiffusion and reaction at polymer/polymer interface in recent years are discussed.Finally

a simple review about application of dynamic rheological technique on interdiffusion at polymer/polymer interface is made.
