Gas separations membranes properties of Cardo poly(imides) statistical and alternating structure

Abstract

Gas Separations Membranes Properties of synthesized new Cardo Poly(imides): homo and copolymers statistical and strictly alternating distribution Cardo Poly (diamines) fragments on a circuit structure for individual gases CO2/N2 are investigated at 22°C and in 25-150°C temperatures interval. Correlation between type of distribution and gas permeability parameters is established. It is shown that the amorphous 4 componental Cardo Poly(imides) with statistical Cardo Poly(diamines) fragments distribution may be perspective materials for Gas Separations Membranes.
