    • 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 polymerized wherein 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.
    • 本发明涉及合成聚(甲基)丙烯酸酯组合物的方法,其中烯属不饱和单体通过含有可转移原子基团的引发剂和包含至少一种过渡金属的一种或多种催化剂在存在下转化成聚合物 可以与金属催化剂或催化剂形成配位化合物的配体,其中相对于烯属不饱和单体的总重量为50-100重量%的式(I)的(甲基)丙烯酸酯的烯属不饱和单体是聚合的,其中R表示氢 或甲基,R 1表示具有8至40个碳原子的直链或支链烷基,R 2和R 3独立地表示氢或式-COOR 1的基团,其中R'表示氢或直链或支链烷基 具有8至40个碳原子,在铜的存在下,聚合共聚物中氧化数(I)和(II)的铜的总浓度 相对于组合物的总重量,调整为<= 200ppm。
