摘要：

Polycarbonate (PC) and poly(methyl methacrylate) are miscible; the beta-relaxation characteristic for PC is strongly reduced in these blends. Based on calorimetric, dielectric, and dynamic mechanical studies, X-ray investigations, volume fluctuations and a computer-aided molecular modelling investigation we conclude that specific interactions exist between the phenyl rings and the ester group in such blends. We also conclude that these interactions contribute to miscibility and that they are the origin of the beta-suppression effect.
