标 题:Synthesis of nanofibers of polyaniline and substituted derivatives
发明人：EPSTEIN ARTHUR J; CHIOU NAN-RONG
权利人:OHIO STATE UNIVERISTY
摘要:Novel, simple methods are presented directed to the synthesis of nanofibers of polyaniline and substituted derivatives. The production of these fibers is achieved via various methods by controlling the concentration of aniline monomer or substituted aniline derivatives or an oxidant in the reaction medium and maintaining said concentration at a level much lower than conventional polyaniline synthesis methods. Methods are disclosed relating to the use of a permeable membrane to control the release of a monomer and/or oxidant as well as a bulk polymerization method.

标 题 :Sorbents and method for synthesis of sorbents intended for removal of radionuclides and toxic trace elements from water
发明人：KLAVINS MARIS; ABRAMENKOVS ANDRIS; ANSONE LINDA
权利人:UNIV LATVIJAS
摘要:The invention relates to synthesis of sorbents for removal of radionuclides and toxic trace elements (e.g. heavy metals, no-metallic elements and metalloids) from waters. The offered method for synthesis of sorbents provides covering natural biomaterial structure acting as sorbent matrix with a layer of synthetic polymer containing functional groups by graft polymerization. The sorbent matrix is derived from peat, sawdust or straw.

标 题:An buffer reactor for the preparation of acrn-sulphate for synthesis of acrylamido tertiary butyl sulfonic acid and process implemented thereon
发明人：SARAF VINOD KUMAR
权利人:VINATI ORGANICS LTD
摘要:The present subject matter provides a buffer reactor system 100, and the method for enabling the production of ACRN-sulphate used in the synthesis of ATBS is disclosed. The system may comprise a tubular reactor 117, a first inlet dip pipe 101, a second inlet dip pipe 102, a sparger 111 and an agitation system 116. The process involves the addition of ACRN through the first inlet dip pipe 101 at a predefined flow rate to the tubular reactor 117, the sulphonating mixture through the second inlet pipe 102 and sparge with the help of a sparger 111. The agitation was done with the help of agitation system 116 at a speed of 100-110 rpm and a tip speed of 4.21-4.63 m/sec. The reaction temperature was maintained with an outer cooling jacket 118 between -15 to -5 °C. The said system and process produces ACRN-sulphate, giving white-colored ATBS with reduced impurities.

标 题 :Method for the synthesis of acrylic (co)polymers from oligomers of acrylic acid
发明人：SUAU JEAN-MARC; CHAMPAGNE CLEMENTINE
权利人:ARKEMA FRANCE
摘要:The present invention relates to the synthesis of an associative acrylic (co)polymer by aqueous emulsion radical polymerization. The (co)polymer contains at least one oligomer of acrylic acid represented by the formula (I): n nwhere n is an integer ranging from 1 to 10. The oligomer is prepared from acrylic acid at a temperature of between 50° C. and 200° C. in the presence of a basic or acid catalyst, water, and polymerization inhibitors. The present invention also relates to the associative acrylic (co)polymer obtained from the method and also to the use of this (co)polymer as a thickener in various formulations.

摘要:The present subject matter provides an agitator reactor system 100 and process implemented thereon for synthesis of acrylamido tertiary butyl sulfonic acid monomer. The system comprises a tubular reactor 117, a first inlet dip pipe 101, a second inlet dip pipe 102, a sparger 113 and an agitation system 116. The process involves the addition of ACRN-sulphate through the first inlet dip pipe 101 at a predefined flow rate to tubular reactor 117, the IB through the second inlet pipe 102, and sparge with the help of a sparger 113 in gaseous form. The agitation is achieved with the help of agitation system 116 at a speed of 170-190 rpm and a tip speed of 2-5 m/sec. The reaction temperature is maintained using an outer cooling jacket 118 between 50 to 60 °C. The said system and process produces the ATBS slurry having white-colored ATBS with reduced impurities.

摘要:The present invention relates to a process for synthesis of polymer compositions with reduced catalyst content, wherein ethylenically unsaturated monomers containing less than 0.5 wt % of ethylenically unsaturated monomers with at least one carboxylic group, sulfonic acid group and/or at least one phosphonic acid group relative to the total weight of the ethylenically unsaturated monomers are polymerized by means of initiators containing a transferable group of atoms and of one or more catalysts comprising at least one transition metal in the presence of ligands which can form a coordination compound with the metal catalyst or catalysts and, after the polymerization, the catalyst contained in the polymer is at least partly separated. For this purpose, the polymer composition is filtered, after the polymerization, in the presence of at least one filter aid which contains at least 0.5 wt %, relative to the total weight of the filter aid, of repeating units that contain at least one carboxylic acid group, sulfonic acid group and/or at least one phosphonic acid group.
