摘要：

The melting behavior of aqueous poly(vinyl alcohol) gels was studied by using small-angle neutron scattering. Emphasis was placed on solutions with a polymer concentration around ϕ, the concentration threshold at which the polymer chains start to overlap. At this particular concentration, a maximum was observed in the polymer-polymer correlation length and the zero angle scattering intensity as the gel was melted. An attempt to interpret this observed maximum in terms of a simple two-phase model will be presented. © 1990, American Chemical Society. All rights reserved.
