New type of highly active chromium(III) catalysts containing both organic cations and anions designed for polymerization of beta-olefin derivatives.

ABSTRACT: The new type of catalysts designed for the olefin derivatives polymerization has been synthetized. The novel catalysts are chromium(III) salt type complexes composed of both organic cation and anion, i.e. [Cr(dipic)₂][Cr(bipy)(dipic)H₂O]∙2H₂O and [Cr(dipic)₂]Hdmbipy∙2.5 H₂O. The compositions of these complexes have been confirmed by a number of instrumental methods including NMR, IR, UV-Vis, MS and elemental analysis ones. Moreover, the crystal structures of these novel catalysts were determined and reported. Furthermore, the [Cr(dipic)₂][Cr(bipy)(dipic)H₂O]∙2H₂O and [Cr(dipic)₂]Hdmbipy∙2.5H₂O complexes have been studied towards their catalytic activity, after the activation by MMA
