## Abstract For solutions of polystyrene (PS) samples of different relative molecular mass (molecular weight) __M__ and intrinsic viscosities [__n__] have been measured at 298,15 K in pure toluene (T) and toluene/methanol (MeOH) mixtures. Upon mixing toluene (good solvent (1)) and methanol (nonsolv

Abstraet--A study was made of the possibility of estimating the compatibility of polymer pairs by means of viscosity measurements of the corresponding ternary systems polymer-polymer-solvent. It was established that there are discrepancies between the intrinsic viscosities of ternary systems and th
The behaviour of ultra-high molecular weight poly(butyl methacrylate) (/~w = 9.59 Γ 106-24.50 Γ 106) in dilute solution in methyl ethyl ketone, benzene, dioxane, and cyclohexanone, at 25c'C. has been investigated by viscometry. Mark Houwink relations have been established, and the unperturbed dimens
