✦ Synopsis

Viscometric, densitometric and light scattering measurements have been performed for poly(methyl methacrylate), poly(n-butyl methacrylate) and poly(cyclohexyl methacrylate) binary mixtures of toluene and n-butyl chloride at 298 K. The total sorption to the polymer chain by the solvents, the Mark-Houwink-Sakurada parameter and the interaction parameter, B, have been determined. Conclusions about the liquid-liquid and polymer-liquid interactions have been drawn, trying to explain the influence of the polymer side group on solution behaviour.
