A theory of dry (containing no solvent) layers of polymer chains grafted onto the internal and external surfaces of an infinite cylinder has been developed. The geometric and thermodynamic characteristics of layers were investigated for two cases: for chains of the same length (monodisperse distribution) and for a mixture of chains of two different lengths (bidisperse distribution). It is shown that the thermodynamic advantage of mixing chains of different lengths demonstrated previously for the case of a planar layer is particularly pronounced for a concave cylindrical layer densely filling a cylindrical pore. The results obtained make it possible to investigate the thermodynamics of superstructures formed by mixtures of diblock copolymers of the AB type with different block length.
