Transient-state theory recently proposed has enabled us to describe the chain length dependence of viscosity of polymeric melts from the Rouse to entangling regimes by the single equation which also takes the factor of temperature into account. On the basis of this theory, this contribution attempts
## Abstract Methyl methacrylate and ethylene glycol dimethacrylate or 1,6βhexanediol dimethacrylate (HDDMA) were copolymerized in the presence of a nonsolvent (heptane) for poly(methyl methacrylate) (PMMA) to examine the phenomenon of polymerizationβinduced phase separations (PIPS) in branched PMMA
## Abstract **Summary:** The effects of viscosity asymmetry of the components on morphology and dynamics of phaseβseparating AB fluids are investigated numerically based on a modified Model H. For critical mixtures, in the early stage of phase separation the coβcontinuous morphology with droplets o
Simulations based on Cahn-Hilliard spinodal decomposition theory for phase separation in thermally quenched polymer/solvent/nonsolvent systems are presented. Two common membrane-forming systems are studied, cellulose acetate [CA]/ acetone/water, and poly(ethersulfone) [PES]/dimethylsulfoxide [DMSO]/
