CHELATES OF 3-ALLYLPENTAN-2,4-DIONE FOR THE SYNTHESIS OF BRANCHED THERMOSTABLE POLYMETHYL METHACRYLATE

Radical polymerization of methyl methacrylate with the addition Cu(II), Ni(II), Co(II) 3-allylpentan-2,4-dione chelates was carried out. It is shown that in case cobalt complex, process occurs at rates comparable to those traditional radical initiator, benzoyl peroxide. The resulting polymethyl has large molecular weights and contains fragments β-diketonates polymer, which graft side chains. branched structure polymer proven based on calculation Zimm-Stockmeier factor. been established obtained basis a higher thermal stability compared sample using
