PROCESS TO STABILIZE A VANADIUM TETRACLORIDE SOLUTION AND PERFECTING IN A CONTINUOUS PROCESS TO POLYMERIZE ONE OR MORE OLEFINS IN AN INERT ORGANIC SOLVENT, USING A VANADIUM COMPOUND AS CATALYST

摘要

Solutions of VCl4 in inert organic solvent are stabilized by incorporation of decomposition retardants being halogenated organic compounds having at least two halogen atoms attached to the same carbon atom and activated by adjacent electron donor groups or carbon-carbon double bonds. One of the especially preferred stabilizers is butyl perchlorocrotonate. The solutions are useful in polymerization processes.
