标题:Synthesis of 1,4-trans-polybutadiene using a lanthanide organic acid salt catalyst
发明人：LYNCH THOMAS J
权利人:BRIDGESTONE CORP
摘要:The invention provides a catalyst composition, comprising: (a) an organolithium compound; and, (b) an organic acid salt of lanthanide series element; wherein: (1) only components (a) and (b) are required to promote the synthesis of 1,4-trans-polybutadiene; (2) the ratio of component (a) to component (b) is selected to maximize formation of the trans structure of said 1,4-trans-polybutadiene; and, (3) components (a) and (b) are selected for enabling further diblock synthesis. The invention further contemplates a process for using the catalyst to synthesize 1,4-trans-polybutadiene and other polymers and copolymers having trans configuration in the conjugated diene monomer contributed units.

权利人:ROHMAX ADDITIVES GMBH
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.

摘要:Three dimensional (3D), porous, Sr(II)/Ir(III) layered double hydroxide materials with a spherical/balls like shape, are composed of nanohexagonal sheets intercalated with 1-(1-hydroxy-4-methyl-2-phenylazo)-2-naphthol-4-sulfonic acid have a number of uses including removing undesirable organic compounds and materials from polluted water. This removal can be accomplished without disturbing the pH of the water, and with high absorption capacity (2000 mg of pollutants/1 mg of LDH). The spherical/ball like materials are easily cleaned and are amenable to being reused several times.
