A relationship between tracer diffusion coefficient, tracer molecular weight, matric molecular weight, matrix concentration, and star functionality (f) is discussed. A coupling model approach was compared with extensive experimental studies of the above relationship for polystyrene tracers diffusing in polyvinylmethyl ether and fluoro-toluene solutions.
