Abstract

Tracer diffusion coefficient, D *, and the Newtonian zero shear-rate viscosity, η0, were measured for a high molecular weight random copolymer (SAN) of styrene and acrylonitrile. As predicted by the reptation model, D *was in agreement with the molecular-weight scaling of M −2w (M w is the weight average molecular weight of the chain being probed) and was independent of matrix molecular weight. η0 showed a molecular-weight scaling of M 3.4W . While the temperature dependence of these two relaxation processes could be well explained by the free-volume model up to 252 °C, they showed a discrepancy in activation enthalpy, E a, of about 20%, with a larger value for diffusion.
