Abstract

We have studied the behavior of interdiffusion between partially miscible polymer pair from a theoretical viewpoint by applying the reptation model for collective interdiffusion and spinodal decomposition in polymer mixtures with different molecular weights. We find that our predictions agree well with the experiments of Klein and co-workers, where the exponent α of the initial increase of interfacial width with time in $t^{\alpha}$ is significantly lower than 0.5 for free diffusion.
