Abstract
High polymers and oligomers of substituted alkenes are made by contacting the monomer with a catalyst comprising (1) an organometallic compound of a metal of Group IV (A) to VIII of the Periodic Table which compound contains at least one p -allylic ligand and a halogenated organic compound. Specified p -allylic compounds include tris-(p -allyl) chromium, bis-(p -allyl) nickel, bis-(p -allyl) palladium, tetra - (p - allyl) molybdenum, tetra - (p -allyl) zirconium, tris - (p - crotyl) chromium, tris-(p -methallyl) chromium and p -allyl iron tricarbonyl iodide. The halogen compound may be CCl4, CHCl3, CCl3Br, dichloroacetic acid, chloral, trichloroacetic acid, trichloroacetonitrile, benzotrichloride, polyvinyl trichloroacetate, and mixtures. Suitable monomers are acrylonitrile, methyl methacrylate, styrene, and n-butyl vinyl ether. The polymerization may be effected in bulk or in the presence of a hydrocarbon diluent. The organometallic compound may be formed in situ. Organic phosphines may also be present with the organometallic compounds. The reaction may be carried out at a temperature between - 30 DEG to 100 DEG C. The examples all relate to formation of high molecular weight polymers.ALSO:The preparations of the following organo-metallic compounds of Cr, Ni, Fe, Pd, Mo, and Zr, containing at least one p -allylic ligand are described in the examples. Tris (p -allyl) chromium by adding anhydrous CrCl3, in ether to allyl magnesium chloride at -30 DEG C., and stirring at -80 DEG C. for several hours. Bis(p -allyl) nickel by adding allyl magnesium chloride to anhydrous nickel chloride suspended in ether. p -Allyl iron tricarbonyl iodide by refluxing allyl iodide and iron pentacarbonyl. Bis-p -allyl palladium by adding allyl magnesium chloride to anhydrous palladium chloride. Tetra (p -allyl) molybdenum by pouring a solution of MoCl5 in ether into a solution of allyl magnesium chloride in ether. Tetra (p -allyl) zirconium by adding anhydrous zirconium tetrachloride in ether to allyl magnesium chloride, under nitrogen at -80 DEG C., and the compound extracted with pentane at -40 DEG to -60 DEG C.
