The gas permeability of 0, and N, for homogeneous and composite membranes prepared from poly(2,6-dimethyl-1,4-phenylene oxide) (PPO) samples with different molecular weight parameters was investigated. Temperature dependencies of gas permeability coefficients and permselectivity were determined for
The viscosity behaviour of dilute benzene solutions of poly(fluorostyrene-co-bromostyrene) (A) and poly(2,6-dimethyl-1,4-phenylene oxide) (B) and of their mixtures has been studied at 25 Β°. The viscosity interaction coefficients, kAs, have been calculated from the Huggins slope coefficients of polym
