TIME AND TEMPERATURE DEPENDENCE OF PHASE-SEPARATION BEHAVIOR FOR POLY(N-METHYL METHACRYLIMIDE)/POLY(VINYLIDENCE FLUORIDE) BLENDS
PMMI/PVDF共混体系相分离的时温依赖性

The liquid-liquid phase-separation(LLPS) behavior of poly(N-methyl methacrylimide)/poly(vinylidene fluoride)(PMMI/PVDF) blends was studied by using small angle laser light scattering(SALLS),and the time-temperature dependence of phase-separation behavior was discussed.According to examining the dependence of cloud points(T_c) on heating rate for PMMI/PVDF blends,it was found that T_c decreased as the temperature droped nonlinearly.When the heating rate was higher than 1.0 K/min,only the heating rate could a...
