Estimating the term…
This invention relates to a process for carrying out an anionically or cationically catalytically accelerated gas phase reaction and particularly relates to a process for carrying out a catalytically accelerated gas phase polymerization reaction. The process involves the step of introducing a catalyst ion into a gaseous reaction mixture as a free anion or cation without a corresponding counterion and substantially solvent free. The catalyst of this invention can, for example, be a Ziegler-Natta catalyst or a metallocene catalyst. The gas phase reaction that is catalyzed can, for example, be a metathesis reaction, a metathesis ring-opening polymerization reaction, or a gas phase polymerization.
A process for carrying out an anionically or cationically accelerated reaction in the gas phase comprising the step of introducing a catalyst ion into a gaseous reaction mixture as a free anion or cation without corresponding counterion and substantially solvent-free wherein the catalyst ion is a Ziegler-Natta catalyst.
A process for carrying out an anionically or cationically accelerated reaction in the gas phase comprising the step of introducing a catalyst ion into a gaseous reaction mixture as a free anion or cation without corresponding counterion and substantially solvent-free wherein the catalyst ion is a metallocene catalyst.
A method for producing a polyolefin in a gas phase reaction which comprises the steps of carrying out an anionically or cationically accelerated reaction in the gas phase in which a catalyst ion is introduced into a gaseous reaction mixture as a free anion or cation without corresponding counterion and substantially solvent-free.
