摘要：
We generalize the de Gennes' theory of the microphase separation of cross-linked polymer mixtures to take into account the spatial fluctuations of the elasticity constant c(r) obeying a Poisson distribution. Within a mean-field analysis we found that for weak fluctuations of c(r) the free energy possesses a minimum corresponding to a microphase separation. The size of the domains is enlarged in comparison to the homogeneous case.
