## Abstract The coupling model is formulated in terms of the dynamic constraint entropy, __S__~__c__~(__t__), and subsequently compared with measured tracer diffusion coefficients __D__ for linear, 3‐arm star, and 12arm star polystyrenes in solutions of poly (vinyl methyl ether) (PVME) /__o__‐fluor
