标 题 :Method for producing elastomeric copolyesters
发明人：KAEMPF RUDOLF
权利人:LURGI ZIMMER GMBH
摘要:A process for continuous or discontinuous synthesis of elastomeric copolyesters from polybutylene terephthalate (PBT) and polyoxytetramethylene glycol is described in which the tetrahydrofuran (THF) obtained as a byproduct in synthesis of polybutylene terephthalate from 1,4-butanediol is rectified and then reacted by ring-opening polymerization to form polyoxytetramethylene glycol which condenses with the free or esterified carboxyl groups of PBT to form the copolyester, whereby chain termination and catalyst deactivation are accomplished by adding 1,4-butanediol without separating the catalyst.

标题:Polymers bearing pendant pentafluorophenyl ester groups, and methods of synthesis and functionalization thereof

摘要:A one pot method of preparing cyclic carbonyl compounds comprising an active pendant pentafluorophenyl ester group is disclosed. The cyclic carbonyl compounds can be polymerized by ring opening methods to form ROP polymers comprising repeat units comprising a side chain pentafluorophenyl ester group. Using a suitable nucleophile, the pendant pentafluorophenyl ester group can be selectively transformed into a variety of other functional groups before or after the ring opening polymerization.

标题:Porous inorganic oxide materials prepared by non-ionic surfactant templating route
发明人：PINNAVAIA THOMAS J; BAGSHAW STEPHEN A
权利人:UNIV MICHIGAN STATE
摘要:A method for the preparation of new semi-crystalline, porous inorganic oxide compositions possessing uniform framework-confined mesopores in the range 2.0-10.0 nm. The method uses an interaction between various nonionic polyethylene oxide based surfactants (N DEG ) and neutral inorganic oxide precursors (I &squ& ) at ambient reaction temperatures. The materials formed exhibit a disordered assembly of worm-like channels of regular diameter owing to the specific mechanism of self-assembly, producing highly stable materials and particles incorporating large numbers of the channels. This (N DEG I DEG ) templating approach introduces several new concepts to mesostructure synthesis. The application of the low-cost, non-toxic and biodegradable surfactants and ambient reaction temperatures, introduces environmentally clean synthetic techniques to the formation of mesostructures. Recovery of the template can be achieved through solvent extraction where the solvent may be water or ethanol.

权利人:UNIV MICHIGAN STATE
摘要:A method for the preparation of new quasi-crystalline, porous inorganic oxide compositions formed in the presence of fluoride ion possessing a disordered assembly of worm-like channels. The method uses an interaction between various nonionic polyethylene oxide based surfactants (N DEG ) and neutral inorganic oxide precursors (I DEG ) in an aqueous solution and then the formation of dispersed particles in the aqueous solution in the presence of fluoride. This (N DEG I DEG F-) templating approach introduces several new concepts to mesostructure synthesis. The application of the low-cost, non-toxic and biodegradable surfactants and ambient reaction temperatures, introduces environmentally clean synthetic techniques to the formation of mesostructures. Recovery of the template can be achieved through solvent extraction where the solvent may be water or ethanol.
