| abstract | Polymers of ethylenically unsaturated hydrocarbon monomers containing three or more carbon atoms are made by effecting the polymerization of the monomers in the presence of a catalyst composition comprising (a) a titanium halide, (b) an organo-aluminium compound of the formula AlRnX3- n where R is a hydrocarbon radical, X is hydrogen or halogen, and n is 2 or 3 and (c) an organic halide selected from (1) compounds of the formula X1X2C = CX3X4 where X1 and X2 are hydrogen or halogen atoms, and X3 and X4 are hydrogen or halogen atoms, or hydrocarbon radicals, with the proviso that at least one of X1, X2, X3 and X4 is a halogen atom, and that the two carbon atoms are substituted with less than four fluorine atoms and less than four chlorine atoms, (2) compounds represented by the formula, X2CAY where A is an aromatic or olefinic radical, X is a halogen atom and Y is halogen, hydrogen or an alkyl group, (3) compounds which include the grouping <FORM:1065607/C3/1> where X represents a halogen atom which is not attached to a carbon atom of an aromatic ring, (4) compounds represented by the formula R1XCR2R2 where X is a halogen atom, R1 is hydrogen atom, halogen atom or saturated hydrocarbon radical, and R2 is a halogen atom or a saturated hydrocarbon radical, and provided that when R1 is a halogen atom, R2 is a hydrogen atom, that when C is a secondary carbon atom, R1 and R2 include a halogen substituted hydrocarbon radical, and that when C is substituted with three fluorine atoms, the remaining substituent is chlorine, bromine, or iodine. The atomic ratio of the organic halide compound to the organo-aluminium is from 0.8 to 100 and the mole ratio of the organo-aluminium compound to the titanium halide is from 0.15 to 10. The preferred catalyst is made by combining the organo-aluminium compound with the chosen amount of organic halide and adding to the mix TiCl3 in an amount sufficient to give a mole ratio of the aluminium compound to the TiCl3 of from 0.5 to 5. Specified monomers are propylene, 1-butene, 1-hexene, 1-octene, 2-pentene, isobutylene, styrene, 2 - methylbutene - 1, 4 - methylbutene-1, 1,5-hexadiene, 1,4-pentadiene, 1,4-octatriene, isoprene, and 2-phenylbutadiene. The titanium halide is preferably TiCl3 or TiCl4. The Specification contains long lists of suitable organic halides. Exemplified halides are 1,2-dibromooctane, p-dodecylbenzyl chloride, benzyl chloride, allyl chloride, tert.-butyl chloride, chloroform, benzotrichloride, p-chlorobenzyl chloride, tert.-butyl bromide, alpha-bromoethylbenzene, bromotrichlormethane, p - bis-(chloromethyl) benzene, propargyl chloride, 1,1,1 - trichloroethane, 1,1,1,5 - tetrachloropentane, 1,1,1 - trichloroethane, bromoform, 1,1,1,5 - tetrachloropentane, 1,1,1 - trichloroundecane, 2,2 - dichloropropane, trichlorofluoromethane, carbon tetrabromide, iodoform, methylene chloride, hexachloroethane, trifluoroiodomethane, trichloroethylene, 1,2,3,-4,5,6-hexachlorocyclohexane, vinyl chloride, 1-bromoethylbenzene, vinyl fluoride, vinylidene chloride, cis and trans ClHC = CHCl, (C6H5)2C = CHCl, and C6H5.HC = CHC6H5. The polymers may be fractionated by solvent extraction. |
