Abstract

The concentration-temperature dependence of loosely cross-linked neutral networks being in equilibrium with pure diluent is studied. It is shown, that the constrained junction fluctuation network model, introduced by Flory and Erman, precludes the possibility of a first order like gel-collapse transition. A simple equation is proposed to describe the dependence of equilibrium swelling degree on the temperature. Experimental results performed on poly(vinyl acetate) networks swollen to equilibrium in isopropyl alcohol are also presented.
