摘要：

Dissolution in a range of solvents reveals two kinds of behaviour readily soluble samples (mostly suspension-polymerized) and partly gel-forming samples (mostly emulsion-polymerized). From molecular characterization of a number of industrial and laboratory samples of the first kind in solution in different solvents by light scattering, intrinsic viscosity and size exclusion chromatography, we derive unperturbed dimensions and chi parameters. Our results differ from previous measurements where light-scattering experiments were carried out in solvents with very low dn/dc and/or on less-soluble (second-kind) PVDF, where microgel formation cannot be avoided.
