Connectivity selection by porous media: "spectral chromatography"

(Received 30 July 1991, accepted in final form 2 September 1992)

Abstract
This note discusses the behavior of polymers with arbitrary connectivity in small pores. For simplicity only cylindrical pores are considered. In contrast to linear polymers (spectral dimension = 1) which fit into very small pores, branched chains with larger spectral dimension require a minimum pore size, which is a function of the molecular weight. This special situation allows for a connectivity selection of mixtures of differently branched and linear molecules by specially designed chromatograph.
