Abstract

Abstract-Influence of 1-[pyridyl-2]-, 1-[quinolin-2-yl]-, 1-[acridin-9-yl]-, 1-[pyrazin-2-yl]-, and 1-[pyrimid-4-yl]-ferrocenes on heat and thermomechanical properties of the produced poly(methyl methacrylate) has been studied.Keywords: azinyl ferrocene, poly(methyl methacrylate), radical polymerization, initiator, thermal properties, thermomechanical properties ISSN 1070-3632, Russian Journal of General Chemistry, 2014, Vol. 84, No. 12, pp. 2472-2474. © Pleiades Publishing, Ltd., 2014.

It was demonstrated that the metal complexes I-V combined with diacyl peroxides (benzoyl peroxide or lauryl peroxide) form highly efficient initiating systems, more active than the systems based on unsubstituted ferrocene [3][4][5], allowing for fast polymerization with high yield at lower temperatures (30-60)°С. The spectral studies confirmed that both ferrocenyl and heterocyclic fragments of compounds I-V affected the coordination with peroxide initiator [2]. LETTERS TO THE EDITORThe mentioned ferrocenes did not interact with azobisisobutyronitrile AIBN but the overall polymerization rate of methyl methacrylate polymerization was somewhat increased, pointing at the influence of the azinyl ferrocenes on the chain growth processes in addition to that on the initiation step [2].
