## Abstract Diffusion coefficient measurements for solvents in concentrated polymer solutions require consideration of both concentration dependence of the diffusion coefficient and surface resistance to mass transport. Solutions to the diffusion equation have been generated where these effects are
## 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
## Abstract In chemical engineering applications involving solvent removal from a concentrated polymer solution where diffusion is the governing process (e.g. dry spinning of synthetic silk‐like fibres), the determination of the concentration‐dependent diffusion coefficient is essential. Diffusion
