Abstract
1,245,507. Polymerizing olefins. SOLVAY & CIE. 13 Nov., 1969 [2 Dec., 1968; 6 Oct., 1969], No. 55626/69. Heading C3P. Olefins are (co)polymerized in the presence of a catalytic system comprising (a) a solid complex produced by reacting a halogenated derivative of a transition metal with a solid support, and (b) an organometallic activator comprising the reaction product of a diolefin and a compound of the formula AlR 3 wherein R is hydrogen or a monovalent hydrocarbon radical, the ratio, P, of the number of radicals derived from said diolefin to the number of radicals R in the said product being between 0 25 and 3. The catalytic systems are preferably used to polymerize at least two alphaolefins (e.g. ethylene with propylene and/or butene-1) optionally with a diolefin (e.g. a non-conjugated aliphatic diene, a non-conjugated monocyclic diene or an alicyclic diene having an endocyclic bridge) to produce a rubbery product. In the examples: (a) ethylene is polymerized in hexane in the presence of hydrogen utilizing reaction products of isoprene and triisobutyl aluminium (having various values of P) and the reaction product of TiCl 4 and a magnesium oxide support; (b) ethylene and butene are copolymerized in hexane in the presence of hydrogen utilizing the reaction product of isoprene and triisobutylaluminium (P= 2) and the reaction product of TiCl 4 and a magnesium carbonate support; (c) ethylene is polymerized in hexane in the presence of hydrogen and titanium tetraoctylate (to give a wide M.wt. range and a low density polymer) using the catalyst specified in (b) above; (d) ethylene is polymerized in hexane and in the presence of hydrogen utilizing a reaction product of triisobutyl aluminium and isoprene (P=2 3) and the reaction product of TiCl 4 and a magnesium hydroxychloride support; (e) ethylene and propylene are polymerized in hexane utilizing the reaction product of triisobutyl aluminium and isoprene (P=1 9) and the reaction product of TiCl 4 and vinyl alcohol/vinyl chloride/vinyl acetate copolymer support; and (f) ethylene and propylene are bulk polymerized utilizing the reaction product of triisobutyl aluminium and isoprene (P =1 9) and the reaction product of TiCl 4 and a magnesium oxide support.
