摘要：

The behaviour of poly(methyl methacrylate)/polyvinylpyrrolidone (PMMA/PVP) blends was investigated by solid state nuclear magnetic resonance (NMR) using proton spin-lattice relaxation time in the rotating frame (T(1)(H)rho), which was measured from the variable contact time experiment. From T(1)(H)rho relaxation measurements scale, it was possible to obtain a response of the degree of intimacy mixture of polymer blend components. Good compatibility was observed for all proportions studied, as a consequence of the interaction process of blends components.
