摘要:A process has been surprisingly discovered that can produce a high heat carbonate polymer (i.e., one with a Tg greater that 150° C.), without the drawbacks encountered in attempts to produce a high heat carbonate polymer. The process of the instant invention comprises the steps of: n (1) reacting an aromatic amine with a dihydric phenol to prepare an aminophenol; n (2) reacting an anhydride or dianhydride with the aminophenol to prepare a phenolic precursor; and n (3) reacting the phenolic precursor with a carbonate precursor to prepare a high heat carbonate polymer.

标 题 :Composite covalent organic framework membranes
发明人：BIKSON BENJAMIN
权利人:Avanpore LLC
摘要:Disclosed is the preparation of composite fluid separation membranes based on poly (aryl ether ketone) (PAEK) polymers with the separation layer formed by a layer-by-layer reticular synthesis. The porous PAEK substrate is semicrystalline, exhibits a mesoporous surface structure, and is surface functionalized. The separation layer formed by the hierarchical layer-by-layer process is in the form of a covalent organic network integrally linked via covalent bonds to the functional groups of the substrate. The composite separation layer may be synthesized in situ in a preformed separation device on the surface of the PAEK substrate. Device configurations include flat sheet, spiral wound, monolith, and hollow fiber configurations with the hollow fiber configuration being preferred. Hollow fibers are formed from PAEK polymers with poly (ether ether ketone) and poly (ether ketone) particularly preferred. Composite PAEK membranes of the present invention are useful for a broad range of fluid separation applications.
