权利人:UNIV WARSZAWSKI
摘要:An initiator of ATRP radical polymerisation having a functional group with a substituent active in polymerisation process, is characterised in that it is a bifunctional initiator containing at least two functional groups separated by a hydrocarbon moiety Y, where the first functional group has an active substituent X and the second functional group has a protecting group Z, which can be chemically modified with the same or a different substituent than the active substituent X present in the first functional group. A method of synthesis of 2-chloro-N-(2-hydroxyethyl)propionamide initiator, NCPAE, is characterised in that ethanolamine is subjected to an acylation reaction with 2-chloropropionyl chloride in presence of triethylamine (TEA), wherein the reaction is carried out under inert atmosphere at room temperature.

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:The present invention relates to processes for synthesis of poly(meth)acrylate compositions, wherein ethylenically unsaturated monomers are transformed to polymers 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, wherein ethylenically unsaturated monomers containing 50 to 100 wt %, relative to the total weight of ethylenically unsaturated monomers, of (meth)acrylates of formula (I) are polymerizedwherein R denotes hydrogen or methyl, R1 denotes a straight-chain or branched alkyl group with 8 to 40, carbon atoms, R2 and R3 independently denote hydrogen or a group of the formula -COOR1, wherein R' denotes hydrogen or a straight-chain or branched alkyl group with 8 to 40, carbon atoms, in the presence of copper, the total concentration of copper of oxidation numbers (I) and (II) in the polymerization composition being <=200 ppm relative to the total weight of the composition.
