Abstract
1478457 Vinyl halide preparation IMPERIAL CHEMICAL INDUSTRIES Ltd 8 July 1974 [19 July 1973] 30150/74 Addition to 1374967 Heading C3P In a process for the gaseous phase polymerization of a vinyl halide, the latter is contacted with a catalyst composition comprising (a) a compound of a transition metal of Groups IVA to VIA of the Periodic Table of Elements and (b) an organoaluminium or organozinc compound containing a ligand derived from a hydroxy ester, the polymerization being effected in the presence of a particulate seed material which comprises a polymer of a vinyl halide. The vinyl halide may be the chloride and bromide, which if desired may be copolymerized. Other copolymerizable unsaturated monomers specified are vinyl acetate, styrene, methyl acrylate, methyl methacrylate, acylonitrile, ethylene, propylene, butene, 4-methylpentene- 1 and butadiene. The catalyst may be supported on the seed material or on, e.g. SiO 2 or Al 2 O 3 . The support materials may have a size of 1- 1000 microns. The process of the invention may be effected in a fluidized bed, e.g. at 40-95‹ C. Examples describe the preparation of P.V.C. in the presence of catalyst compositions disclosed in Specification 1,374,967.
