Synthesis of Ultrahigh Molecular Weight Polyethylenes with New Catalyst Based on Ti4+ Complex with a Tridentate Phenoxyimine Ligand
A novel catalyst system containing a complex of Ti4+ with a (O,N,O)-tridentate phenoxyimine ligand and a binary Al(C2H5)2Cl/Mg(C4H9)2 activator at a molar [Al]/[Mg] ratio of ~3 affords the synthesis of ethylene polymers with molecular weight in excess of 1 × 106. Ethylene homopolymer produced at 35°C has Mw ~ 2.6 × 106 and ethylene copolymers with small amounts (below 1 mol %) of 1-hexene, 1-octene and 1-decene have Mw ~ 1.5 × 106. The polymers have a relatively narrow molecular weight distribution (Mw/Mn ratio from 3.5 to 5), their mechanical properties are similar to properties of commercial UHMW polyethylenes.
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
