Abstract	THE PHASE SEPARATION BEHAVIOR OF POLYVINYL METHYL ETHER) / POLYSTYRENE SEMI-IPN FEBRUARY 1990 OSAMU AOKI, B. S., KYOTO UNIVERSITY, JAPAN M. S., KYOTO UNIVERSITY, JAPAN Ph. D., UNIVERSITY OF MASSACHUSETTS Directed by: Professor Richard S. Stein The effect of crosslinking on the phase stability and phase separation behavior of poly(vinyl methyl ether) / polystyrene semi-IPN was studied by light scattering. The cloud point temperature was measured as a function of degree of crosslinking and found to be constant within experimental precision. The result of this experiment was combined with a theoretical prediction of the phase diagram to determine conditions for the following experiment. Wide angle light scattering was used to quantitatively analyze the mechanism and dynamics of the thermally induced phase separation with respect to the crosslinking density and the thermal condition. An apparatus with a one dimensional diode array was used to simultaneously monitor a wide range of scattering angles.
