摘要：
The compatibility of components in the PC (M-w = 2.5 x 10(4))-PMMA (M-w = 1.5 x 10(4), 7.4 x 10(4), 30 x 10(4)) blend at a temperature above the T-g of PC was studied by the microinterference method. The constructed phase diagrams are shown to contain an UCST. For the PC-PMMA system (M-w = 1.5 x 10(4)), the kinetics of diffusion mixing and viscosity properties (at T = 240 degreesC) were characterized at different points of the phase diagram. The corresponding dependence of viscosity on composition shows a local minimum near a binodal at a higher content of PC.
