Polymerization of vinyl monomers initiated by the binary system cobaltocene/bis(ethyl acetoacetato)copper(II), Related Products of copper-catalyst, the publication is Makromolekulare Chemie (1984), 185(8), 1493-505, database is CAplus.

The effect of some metallocenes such as ferrocene  [102-54-5], nickelocene  [1271-28-9], and cobaltocene (I) [1277-43-6], on the vinyl polymerization initiated with bis(Et acetoacetato)copper(II) (II) [14284-06-1] was investigated. I exerted a markedly accelerating effect on the polymerization of methyl methacrylate (III) [80-62-6] with II. The polymerization of III with I–II system at 50° was affected by the solvent used. The results of copolymerization of III with styrene and the effect of hydroquinone on the polymerization of III with I–II showed that the polymerization proceeds via a radical mechanism. The polymerization of III with I–II was studied kinetically in acetone. The overall activation energy of the polymerization was calculated to be 20.6 kcal/mol. This value was somewhat higher than that (17.6 kcal/mol) obtained for the polymerization of III with II alone. The polymerization rate (Rp) is represented by the equation: Rp = k[I]0.5[II]0.2[III]1.3. The high order in monomer concentration suggests a participation of the monomer in the initiation process. This is supported by the examination of the ESR spectrum of the system I–II–III-acetone, where reduction of Cu(II) to Cu(I) occurs. To elucidate the initiation mechanism, the spin trapping technique was applied to the system I–II-Me acrylate. From these results, an initiation mechanism for the binary initiator system I–II is proposed and discussed.
