Abstract

The temperature dependence of equilibrium concentration of swollen polyvinyl acetate gels was studied below and above the theta temperature. Collapse was not observed. An analysis of the classical gel theories as well as the experimental results has shown that the James-Guth theory is adequate to describe the experimentally found universal dependence of phi // theta / phi on tau / phi // theta (where phi is the equilibrium concentration of the gel, tau is the reduced temperature and the theta subscript refers the theta state). It was also found that upon cooling below the theta point a continuous non-phase transition occurs.
