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