Popis:	The kinetics of component formation and phase separation for the in situ preparation of aerosil-filled blends of linear PU and linear PS is studied. The introduction of a filler into the PU-PS system increases the rate of PS formation. This feature distinguishes this system from the previously studied PU-PMMA system, where the introduction of aerosil reduces the rate of PMMA formation. This effect may be associated with a decrease in the mobility of blend components that is related to introduction of the filler, which leads to more viscous systems, and with differences in conditions of the in situ polymerization of styrene and methyl methacrylate in the blend with the PU being formed. The acceleration of phase separation in the PU-PS system with an increase in the PS content may be explained by the preferential adsorption of PU on aerosil.
