Abstract
1,212,428. Four or more component Zeigler catalyst for olefin polymerization. SCHOLVEN-CHEMIE A.G. 9 Aug., 1968 [12 Aug., 1967], No. 38243/68. Heading C3P. α-Olefins are polymerized by contacting with a catalyst comprising (a) coprecipitated titanium and vanadium compounds, (b) an organometallic compound of Groups I to III and (c) an alkyl zinc or cadmium compound, the molar ratio of (b) to (c) being between 1: 1 and 100: 1. Component (c) may be a zinc alkyl halide or dialkyl zinc or mixture thereof. In the examples the catalysts employed are Al(C 2 H 5 ) 3 - BF 3 - TiCl 4 - VOCl 3 - Al(C 2 H 5 ) 2 Cl or Al(C 2 H 5 ) 2 F - Al(C 2 H 5 ) 2 Cl - TiCl 4 - VOCl 3 - further Al(C 2 H 5 ) 2 Cl or Ti(OC 3 H 7 ) 4 - vanadium chloride - (C 2 H 5 ) 2 AlCl - further (C 2 H 5 ) 2 AlCl, together with Zn(C 2 H 5 ) 2 or Cd(C 2 H 5 ) 2 , Al(C 2 H 5 ) 3 , and Al(C 2 H 5 ) 2 Cl, in the homopolymerization of ethylene and copolymerization with butene.
