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 :Process for synthesis of polymer compositions with reduced halogen content, polymer composition with reduced halogen content as well as use of this composition
发明人：ROOS SEBASTIAN; BOLLINGER JOSEPH MARTIN; SCHERER MARKUS
权利人:ROHMAX ADDITIVES GMBH
摘要:Polymer compositions with reduced living halogen content are used as additive to lubricating oils and are prepared by polymerizing at least one ethylenically unsaturated monomer using a) at least one initiator containing a transferable halogen and b) one or more metal catalysts containing at least one transition metal, in the presence of ligands which can form a coordination compound with the one or more metal catalysts, to obtain a polymer composition having a living halogen content, and after the polymerizing, reacting the polymer composition having a living halogen content with at least one organic nitrogen compound in the presence of a nonpolar solvent, thereby reducing the living halogen content to obtain the polymer composition having a reduced halogen content.

摘要:The invention relates to a process for preparing polymers for coating applications by polymerizing esters of acrylic acid or of methacrylic acid or vinyl aromatics or other free-radically polymerizable vinyl compounds or monomer mixtures composed predominantly of such monomers by means of a continuous polymerization process. In particular, the invention relates to a solvent-free preparation process for polymers, through which the binder can be prepared for coating applications with superior processing properties, very good thermal stability, improved pigment wetting and a higher gloss.
