Abstract
Liquid-liquid demixing, following spinodal quenches of poly-2-chlorost yrene/polystyrene blends, was followed by light scattering at 632.8 nm . The dependences of demixing on H/D substitution and molecular weight of the polystyrene, and on pressure, are reported. In the region of i nterest, the phase diagram is of the lower critical solution (LCS) typ e, and demixing is induced by raising the temperature. The transition temperature is lowered by deuterium substitution. At constant quench d epth the transition proceeds more rapidly at elevated pressure. (C) 19 95 John Wiley and Sons, Inc.
