Received Date: 17 December 1996

Excimer formation of pyrene and benzyl 4-(1-pyrenyl) butanoate was used to study the microviscosity of polystyrene/toluene solutions over the entire concentration range.Two critical concentrations (C_PS~0.32,0.82g/ml) have been observed from the log-log plot of I_E/I_M vs C_PS.The results are explained in terms of the onset of cohesional interaction and the glass transition of the polymer chains,respectively.
