Abstract

Measurements are made of the osmotic swelling pressure and small angle X-ray scattering from lightly crosslinked poly(vinyl acetate) (PVAc) gels swollen in toluene and containing known amounts of free PVAc chains. Gels with different amounts of free chains, but with identical total polymer concentration, exhibit similar behaviour. The differences observed between the thermodynamic properties of the gels and the solutions are consistent with a reduction in the fraction of polymer participating in the dynamic concentration fluctuations.
