Abstract
"Thermodynamic slowing down" effects on interdiffusion are demonstrated in binary mixtures of normal and deuterated polystyrene. The interdiffusion coefficient is shown to undergo a minimum in the vicinity of a critical blend composition . This effect increases with decreasing temperature.
