Mechanism of phase separation of polystyrene gels disturbed and not disturbed by a mechanical field

Abstract

The phase equilibrium of PS gels with a network of different density in cyclohexane in the non-deformed state in conditions of uniaxial stretching and all-sided compression has been studied. The pulsing mechanism of phase separation of the gels was found manifest in the fluctuational character of the rate of their clouding, squeezing out of the solvent and non-monotonic change in their geometric dimensions and also the radii of the light-scattering particles.
