摘要：
Small angle neutron scattering (SANS) measurements have been carried out on chemically crosslinked poly (vinyl acetate) gels. The scattering spectra are analysed in the framework of a model, which consists of a liquid-like component given by an Ornstein-Zernike scattering function, plus a static component, given by a stretched exponential form factor. The thermodynamic interaction parameters deduced from the liquid-like component of the gel signal are compared with the results of independent osmotic swelling pressure and mechanical measurements.
