Molecular interaction in some polymeric additive solutions containing styrene-hydrogenated butadiene copolymer
The miscibility of styrene-hydrogenated butadiene copolymer (SHB) with different constituents of polymer additives for lubricating mineral oils was studied in dilute solution regime, using xylene as model solvent, at 30 oC, in a wide range of polymer blend compositions. The systems studied were SHB / poly(ethylene-co-propylene) (EPC), SHB / poly(methyl methacrylate) (PMMA), SHB / poly(dodecyl methacrylate) (PDDMA) and SHB / polystyrene (PS). The viscometric interaction parameters were calculated according to the Krigbaum-Wall and Catsiff-Hewett models of ideal viscometric behavior. Strong repulsive interactions were found in SHB / PMMA and SHB / PDDMA systems pointing to immiscibility. SHB / EPC and SHB / PS deviated much less from ideality. The results were compared to the theoretical estimation of interaction in polymer blends in the absence of solvent, using the Coleman-Graf-Painter approach. No correlation was observed between the interaction in the bulk and in solution.
