THE CHARACTERISTICS OF RADICAL POLYMERIZATION OF METHYL METHACRYLATE INITIATED BY COBALT (II) 5-METHYL- 5-HEXENE-2,4-DIONATE

Abstract

The polymerization kinetics methyl methacrylate initiated by cobalt (II) 5-methyl-5-hexene-2,4-dionate has been investigated. Considerable decrease of polymerization rate in comparison with other vinyl-β-diketonates has been shown. The soluble macroinitiators appear during the concentration of 1·10-3 mol/l chelate. Their efficiency in the processes of the styrene grafting is considerably higher, than for polystyrene macroinitiators.
