摘要：

The power-law dependences of critical amplitudes on molar mass for coexistence curve, correlation length and susceptibility have been derived from a Landau-Ginsburg-Wilson type model for chain-molecule solutions of both small molecules and polymers. A series of turbidity measurements and determinations of coexistence curves for solutions of n-alkane in polar liquids and polymethylmethacrylate in 3-octanone have been conducted. Our experimental results and those of polystyrene solutions indicate that this model is satisfied within experimental errors. (C) 1998 Elsevier Science B.V.
