The intrinsic and zero shear viscosity af Nylon-12 is investigated in a mixture of carbon tetrachloride and phenol (1:1 by weight:, and in metacresol at 298-348K temperature range. The variation in viscosity with temperature is explained in terms of entanglement among the polymer molecules and the thermodynamic quality of the solvents. The results so obtained are scaled using a reducing parameter proposed by Faloch. It is found that this parameter works very well over the entire range of concentration and temperature investigated, even in mixed solvents.
