Research Abstract

The glass transition of polystyrene (PS) dissolved in mesitylene (MSL) was studied. The complex shear modulus of the polystyrene solutions was measured over a wide temperature range. The modulus data were time-temperature superposed to construct the composite curve. The frequency dependence of the modulus corresponding to the glass transition of polystyrene was well described by the linear damped torsional oscillator model, suggesting that the chain connectivity of PS governs the glassy relaxation in the solutions and the inter-chain interaction has a minor effect on this relaxation, which is quite different from the situation in bulk PS.
