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.
期刊介绍:
Theoretical and Experimental Chemistry is a journal for the rapid publication of research communications and reviews on modern problems of physical chemistry such as:
