摘要:
By modifying existing methods for synthesizing polyaniline, a polyaniline polymer having a new constellation of material properties has been produced. The material properties of the polymeric compositions disclosed herein enhance the use of polyanilines in a wide variety of processes that use such materials, for example processes used in the formation of filtration membranes.
摘要:
The present invention is directed toward a composition comprising a polyamine or its polymer blend and at at least one salt of an aminoacid, the salt of the aminoacid being present in an amount ranging from about 10 to 80 wt.% based on the total weight of the composition. Another embodiment of the present invention comprises a membrane suitable for use in separating CO2 from gas streams containing CO2, especially H2 rich gas streams containing CO2 and CO. The membrane of this invention with polyamine shows higher CO2 selectivity and permeability than the prior membrane without polyamine.
