ポリマー組成物の製造方法並びに使用
Document Type and Number:
Japanese Patent JP4049313
Kind Code:
B2
Abstract:
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.
