Title
(EN) POLYETHER POLYMERIZATION PROCESS
(FR) PROCÉDÉ DE POLYMÉRISATION DE POLYÉTHER
Abstract
(EN)
Catalyst complexes include a zinc hexacyanocobaltate with M5 metal and M6 metal or semi-metal phases, wherein M5 metal is gallium, hafnium, manganese, titanium and/or indium and the M6 metal or semi-metal is one or more of aluminum, magnesium, manganese, scandium, molybdenum, cobalt, tungsten, iron, vanadium, tin, titanium, silicon and zinc and is different from the M5 metal. The catalysts are highly efficient propylene oxide polymerization catalysts characterized by rapid activation, short times to the onset of rapid polymerization and high polymerization rates once rapid polymerization has begun.

L'invention concerne des complexes catalyseurs comprenant un hexacyanocobaltate de zinc renfermant des phases de métal M5 et de métal ou semi-métal M6, le métal M5 étant le gallium, l'hafnium, le manganèse, le titane et/ou l'indium et le métal ou semi-métal M6 en étant un ou plusieurs parmi l'aluminium, le magnésium, le manganèse, le scandium, le molybdène, le cobalt, le tungstène, le fer, le vanadium, l'étain, le titane, le silicium et le zinc et étant différent du métal M5. Les catalyseurs sont des catalyseurs de polymérisation d'oxyde de propylène hautement efficaces caractérisés par une activation rapide, des temps courts jusqu'au début d'une polymérisation rapide et des vitesses de polymérisation élevées une fois que la polymérisation rapide a commencé.
