Effective-medium Gaussian-chain theory for semidilute polymer solutions confined to a slit
The Gaussian chain theory especially of the second-order approximation was used to decribe the density profiles and the partition coefficients of the chain dimensions perpendicular to the slit walls for polymer chains confined to a slit space. The strength of the theory is its capability to treat a biomodal polymer solution that consists of homologous polymers differing in length.
