标题 :Process for synthesis of polymer compositions, polymer compositionS obtainable by the process, and use of the same
发明人：ROOS SEBASTIAN; EISENBERG BORIS; HARPE CAROLIN
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.

标题 :Solid phase synthesis method and reagent
发明人：SWANSON MELVIN J
权利人:SURMODICS INC
摘要:A reagent composition adapted to be coated onto a support surface in order to provide that surface with a high density of reactive groups. The surface, thus coated, can be used for any suitable purpose, and is particularly well suited for use as a solid phase synthesis support surface. The synthesis support surface, in turn, can be used in repetitive and combinatorial syntheses such as the synthesis of polynucleotides, polypeptides and polysaccharides. The polymeric coating can be used to provide increased effective surface area, particularly in situations in which the effective area of the support surface is itself limited, as on the surface of a silicon wafer. In so doing, the polymeric coating provides an optimal combination of such properties as reactive density and surface area or volume.
