摘要：

The behaviour of poly(ethyl methacrylate) in the system ethyl acetate (1)/iso-propanol (2) is studied; liquid 1 is a solvent for the polymer and liquid 2 is a precipitant. The techniques laser light scattering, differential refractometry and viscometry are used. Preferential adsorption of 2 over the whole composition range is observed as well as a remarkable influence of temperature on the inter- and intra-molecular interactions of the system. Various theoretical expressions for the preferential and total adsorption coefficients are used; their agreement or disagreement with the experimental results is explained on the basis of polymer-solvent interactions. © 1990.
