    • The present invention relates to a process for radically curing a composition comprising a methacrylate containing compound (a1) and a monomer copolymerizable with said methacrylate containing compound in the presence of a 5 transition metal compound (c) and a peroxide, wherein the composition comprises a compound (b) according to formula (1) as monomer copolymerizable with said methacrylate containing compound whereby n= 0-3; R 1 and R 2 each individually represent H, C 1 -C 20 alkyl, C 3 -C 20 cycloalkyl, C 6 -C 20 aryl, C 7 -C 20 alkylaryl or C 7 -C 20 arylalkyl; X = O, S or NR 3 whereby R 3 = H, C 1 C 20 alkyl, C 3 -C 20 cycloalkyl, C 6 -C 20 aryl, C 7 -C 20 alkylaryl, C 7 -C 20 arylalkyl, part of a polymer chain or attached to a polymer chain, and the composition comprises at least one transition metal compound (c) selected from the group consisting of Co, Cu, Mn and Fe compounds, and the curing is effected in the presence of a peroxide selected from the group consisting of hydroperoxides, perketals, peresters, percarbonates and mixtures thereof.
    • 本发明涉及一种在5过渡金属化合物(c)和过氧化物的存在下自由基固化包含含甲基丙烯酸酯化合物(a1)和可与所述含甲基丙烯酸酯化合物共聚的单体的组合物的方法,其中组合物包含 作为可与所述含甲基丙烯酸酯化合物共聚的单体的根据式(1)的化合物(b),其中n = 0-3; R1和R2各自独立地表示H,C1-C20烷基,C3-C20环烷基,C6-C20芳基,C7-C20烷基芳基或C7-C20芳基烷基; X = O,S或NR 3,由此R3 = H,C1C20烷基,C3-C20环烷基,C6-C20芳基,C7-C20烷基芳基,C7-C20芳基烷基,或连接到聚合物链的聚合物链的一部分, 包含至少一种选自Co,Cu,Mn和Fe化合物的过渡金属化合物(c),并且在选自以下的过氧化物的存在下进行固化:选自氢过氧化物,庚酮,过酸酯,过碳酸盐和 其混合物。
