摘要

苯乙烯和 5-甲基-5-己烯-2,4-二酮的共聚物在二甲基甲酰胺中与氯化钴络合时,会形成两种类型的金属聚合物,即分子内和分子外结合的 β-二酮基团,其比例取决于初始大分子配体的浓度。研究证实,聚合物金属配合物在配位单元的几何形状、分子量和金属含量方面存在差异,因此在引发甲基丙烯酸甲酯的接枝自由基聚合反应时具有不同的反应活性。

Cobalt(II) Metallopolymers with 5-methyl-5-hexene-2,4-dione Immobilized on a Polystyrene Matrix as Initiators of Radical Polymerization of Metyl Methacrylate

Cobalt(II) Metallopolymers with 5-methyl-5-hexene-2,4-dione Immobilized on a Polystyrene Matrix as Initiators of Radical Polymerization of Metyl Methacrylate

Cobalt(II) Metallopolymers with 5-methyl-5-hexene-2,4-dione Immobilized on a Polystyrene Matrix as Initiators of Radical Polymerization of Metyl Methacrylate

Complexation of a copolymer of styrene and 5-methyl-5-hexene-2,4-dione with cobalt chloride in dimethylformamide occurs with the formation of metallopolymers of two types, namely with intra- and extramolecular binding of β-diketone groups, the ratio of which depends on the concentration of the initial macromolecular ligand. It has been established that the polymer metal complexes differ in the geometry of the coordination unit, molecular weights, and metal content resulting in the different reactivity to initiation of graft radical polymerization of methyl methacrylate.
