Vinyl polymerization initiated with bis(ethyl acetoacetato)copper(II) and maleimide, Computed Properties of 14284-06-1, the publication is Journal of Macromolecular Science, Chemistry (1981), A16(5), 1017-32, database is CAplus.
Some electron-accepting compounds such as maleimide (I) [541-59-3], maleic anhydride (II) [108-31-6], and tetracyanoquinodimethane [1518-16-7] showed pronounced accelerating effects on vinyl polymerization initiated with metal chelates. The polymerization of Me methacrylate (III) [80-62-6] initiated with bis(Et acetoacetato)copper(II) (IV) [14284-06-1] and I was studied kinetically in C6H6. The overall activation energy of the polymerization was 11.5 kcal/mol. This value was much lower than that (17.6 kcal/mol) for the polymerization of III with IV alone. The polymerization rate (Rp) was expressed as Rp = k[I]1/2[IV]1/2[III]. The first-order dependence of Rp on the monomer concentration indicated that the monomer had no participation in the initiation step, in contrast with polymerization in the absence of I (where a monomer concentration dependence of 1.4th order was observed). Electron spectroscopic studies revealed that a I–IV complex was formed. The ligand radical, an acetylcarboethoxymethyl radical, was trapped by 2-methyl-2-nitrosopropane in the reactions of IV with I and with II in benzene. From these results the mechanism of the initiation of polymerization was discussed.
