摘要： The invention is a membrane comprising a dense skin of a polyestercarbonate, wherein the diphenolic residue in the backbone of the polyestercarbonate is a tetrabromo diphenolic residue, wherein the membrane has a separation factor for oxygen and nitrogen of 6.5 or greater at 24°C. In another aspect, the invention is a method of separating oxygen from a mixture of gases comprising nitrogen and oxygen, wherein the method comprises (a) contacting the gas mixture with one side of a thin, non-porous membrane comprising a polyestercarbonate described hereinbefore while maintaining a pressure difference across the membrane with the lower pressure being on the other side of the membrane; and (b) removing the permeated oxygen from the other side of the membrane, wherein separation factor for the oxygen and nitrogen is 6.5 or greater at 24°C. The membranes of this invention demonstrate surprisingly high separation factors for oxygen and nitrogen separations. The membranes of this invention have good mechanical properties and therefore are useful under more extreme conditions, for example temperature and pressure, than many commercially used membranes.

摘要： This application relates to copolyerstercarbonate polymers which are prepared with diaryl dicarboxylic acid compounds, particularly biphenyldicarboxylic acid compound. Such copolyestercarbonate polymers show good physical properties including high glass transition temperatures and low ultraviolet radiation sensivity. The thermoplastic copolyestercarbonates can be used to prepare films or molded articles or blended with other thermoplastic resins to give thermoplastic polymer blends for molding purposes.

摘要： An improved gas separation membrane comprises a thin discriminating layer consisting predominantly of a carbonate polymer derived from a bisphenol corresponding to formula I
wherein R at each occurrence is independently H, CI, Br, or C 1 -C 4 alkyl and R 1 is -CO-, -S-, -SO 2 -, -0-, a C 1 -C 6 divalent hydrocarbon radical, or a C 1 -C 6 divalent fluorocarbon radical, or inertly substituted C 1 -C 6 divalent hydrocarbon radical, with the proviso that at least 25 weight percent of the moieties derived from the bisphenol of formula I present in the discriminating layer bear R groups which are exclusively Br or CI, said gas separation membrane exhibiting a separation factor for oxygen and nitrogen at the ambient temperature of at least 6.1. The membrane has particular application to separating oxygen from nitrogen, or a nitrogen-containing gas. •
