RHEOLOGY STUDIES ON THE PHASE BEHAVIOR OF TWOPHASE POLYMER SYSTEMS Ⅰ. PHASE SEPARATION IN BLENDS OF HOMOPOLYMERS
he dynamics of liquid-liquid phase separation of two polymer blends ofpolystyrene/poly (vinyl methe ether) (PS/PVME ) and chlorinatedpolyethylene/ ethylene - vinyl acetate co polymer (CPE / EVA ) was studied bytime-resolved rheometrics meChanical spherometer in spinodal decomposi non (SD) regions. It was found that in the early stage of SD
the dynamicmodulus (G' ) and the dynamic viscosity (n' ) increased with time after the initiation of the isothermal phase mparation; in the intermediate and later stage
G'and η'decreased as the phaseseparation proceeded. This behavior was analyzed and explained in the context of Doi-Edwards model by considering the factors of phase-size increasing
phase bursting and rotating under the shear motion.At the same time
the concept of Dickie's effective volume was introduced to manifest this phenomenon. However
blends of CPE/EVA (25/75
wt/wt) and PS/PVME (90/10
wt/wt)
the dynamic viscosity increased slightly in the later stage.it needs further more detailed studies.
