Alkene Polymerization with Catalysts Containing Ionic Complexes [2L·M@dibenzo-18-crown-6]+[TiCl5·L]– (L = CH3CN, M = Li+, K+)
The polymerization of ethylene and propylene and the copolymerization of ethylene with 1-octene with novel type of post-metallocene catalysts containing ionic complexes [2L·M@dibenzo-18-crown-6]+ [TiCl5·L]– (L = CH3CN, M = Li, K) are studied. The binary activator Al(C2H5)2Cl/Mg(C4H9)2 at [Al] : [Mg] ~ 3 is used as a cocatalyst. A linear crystalline polyethylene, an almost fully amorphous, atactic polypropylene, and statistical ethylene-1-octene copolymers containing from 2 to 9 mol % 1-octene are synthesized. The copolymers exhibit a broad molecular-weight distribution and a nonuniform composition distribution like copolymers synthesized over classical Ziegler–Natta catalysts and many post-metallocene systems.
期刊介绍：
Polymer Science, Series B is a journal published in collaboration with the Russian Academy of Sciences. Series B experimental and theoretical papers and reviews dealing with the synthesis, kinetics, catalysis, and chemical transformations of macromolecules, supramolecular structures, and polymer matrix-based composites (6 issues a year). All journal series present original papers and reviews covering all fundamental aspects of macromolecular science. Contributions should be of marked novelty and interest for a broad readership. Articles may be written in English or Russian regardless of country and nationality of authors. All manuscripts are peer reviewed
