The miscibility and intermolecular interactions between polystyrene (PS) and poly(ethylene-co-propylene) (EPC); as well as between PS and long-chain poly(alkyl methacrylates) (PAMA); namely; poly(dodecyl methacrylate) (PDDMA) and poly(octadecyl methacrylate) (PODMA); in dilute xylene solutions at 30 °C were studied. Investigated polymers are widely used as rheology modifiers; i.e. viscosity index improvers and pour point depressants for lubricating mineral oils. The specific and reduced viscosities of two- and three-component polymer solutions as well as intrinsic viscosities and Huggins' parameter values were determined as functions of the polymer mixture composition and overall polymer concentration. The reduced viscosity was found to be linearly dependent on the overall polymer concentration. The observed viscosities of polymer mixtures were intermediate to those of the mixture constituents; the values decrease in the order: EPC > PS > PAMA. The specific viscosities of all the polymer mixtures obtained as the experimental results and calculated applying the Catsiff-Hewett and Krigbaum-Wall theoretical equations were considered. Since all the polymer/polymer pairs showed the negative viscometric interaction parameter values (Δb12 12; were; 5.47; 6.42 and 13.1 J cm-3 for PS/PDDMA; PS/PODMA and PS/EPC; respectively. © 2005 Elsevier Ltd.
