Patent application numberDescriptionPublished
20090043024POLYCARBONATE NANOCOMPOSITES - Nanocomposites comprising a sulfonated telechelic polycarbonate and an organically modified clay are disclosed. The polycarbonate nanocomposites have improved physical and mechanical properties.02-12-2009
20090043069ACTIVATED ESTERS FOR SYNTHESIS OF SULFONATED TELECHELIC POLYCARBONATES - A process of making a sulfonated telechelic polycarbonate is described. A dihydroxy compound, a carbonate ester, and an activated ester of a sulfobenzoic acid salt are reacted together. The method results in a sulfonated telechelic polycarbonate which has a high percentage of sulfonated end groups, is soluble, and is transparent.02-12-2009
20090043071SULFONATED TELECHELIC POLYCARBONATES - A sulfonated telechelic polycarbonate is described which is produced by melt synthesis. A dihydroxy compound is reacted with a sulfobenzoic acid salt, then with an activated carbonate. The method results in a sulfonated telechelic polycarbonate which has a high percentage of sulfonated end groups, is soluble, and is transparent.02-12-2009

Patent application numberDescriptionPublished
20080269396TELECHELIC POLYESTER/POLYCARBONATE/ORGANOCLAY NANOCOMPOSITES, AND RELATED METHODS AND ARTICLES - A composition comprises, based on the total weight of the composition, from 30 to 50 weight percent of an ionomeric telechelic polyalkylene ester comprising from 0.05 to 5 mole percent of sulfonate end groups; from 50 to 70 weight percent of a polycarbonate; from 0.1 to 10 weight percent of an organoclay; and from 2 to 12 weight percent of an impact modifier.10-30-2008
20090163692AROMATIC POLYETHERS - An aromatic polyether comprising structural units derived from a halosulfone sulfonate having structure (I):06-25-2009
20100029864POLYARYLETHER COMPOSITION AND MEMBRANE - A composition including a polyarylether copolymer is provided. The copolymer includes a polyarylether backbone; and a sulfonated oligomeric group bonded to the polyarylether suitable for use as a cation conducting membrane. Method of bonding a sulfonated oligomeric group to the polyarylether backbone to form a polyarylether copolymer. The membrane may be formed from the polyarylether copolymer composition. The chain length of the sulfonated oligomeric group may be controlled to affect or control the ion conductivity of the membrane.02-04-2010
20100056693Process for Synthesis of Imidazolium and Benzimidazolium Surfactants and their use in Clays and Nanocomposites - The invention relates to compositions of a semicrystalline thermoplastic and a dispersed phase of an organically modified clay, as well as a process for making the organically modified clay, which comprises contacting the clay with at least one imidazolium salt having two long alkyl chains, or a benzimidazolium salt having two long alkyl chains in the presence of a solvent, and recovering the organically modified clay having a d-spacing of clay intercalates of at least 28 Å and thermal stability at 300° C.03-04-2010
20100204431METHOD OF MAKING AN AROMATIC POLYETHER COMPOSITION USING PHOSPHAZENIUM SALT PHASE TRANSFER CATALYSTS - A method for carrying out a chemical reaction between at least two reactants occupying separate phases within a multiphase reaction mixture has been discovered in which at least one phosphazenium salt is employed as a phase transfer catalyst. The remarkable utility of phosphazenium salts as phase transfer catalysts is illustrated by the preparation of aromatic ethers. The phosphazenium salt phase transfer catalysts are shown to be especially useful in the preparation of aromatic polyethers such as polyether sulfones.08-12-2010
