1394378 Polymerisation catalyst SOLVAY & CIE 8 Dec 1972 [8 Dec 1971 1 June 1972] 56719/72 Heading BIE [Also in Division C3] A solid catayltic complex for the polmerisation of olefin is obtained by reaching (i) an oxygen-containing organic compound of a metal of Groups Ia, IIa, IIIb (including boron), IVb (including silicone), VIIa or VIII, (ii) an oxygen-containing organic compound of a metal of Groups IVa, Va, or VIa and (iii) an aluminium compound containing at least one aluminium-halogen bond. A mixture of compounds may be used as component (i) or (ii) 'the three components of the solid complexes may be reacted by mixing simultaneously, mixing (i) and (ii) and subsequently adding (iii), or by mixing (ii) and (iii) and subsequently adding (i). In the examples, ethylene is homopoly merised or copolymerised with propylene in the presence of organoaluminium compounds and of catalytic complexes obtained from (i) Mg(OC 2 H 5 ) 2 , KOC 2 H 5 , Ca(OC 2 H 5 ) 2 , Al(OC 3 H 7 ) 3 , Si(OC 4 H 9 ) 4 , Mn(OC 2 H 5 ) 2 , Fe(OC 2 H 5 ) 3 , Mg(OC 2 - H 5 ) 2 /Al(OC 2 H 5 ) 3 , Mg(OC 6 H 5 ) 2 , Mg(OOCH) 2 , Mg(OH)(OCH 3 ), Mg acetylacetonate, or Mg- (OC 2 H 5 ) 2 ,/Al(OC 4 H 9 ) 3 , (ii) Ti(O-n-C 4 H 9 ) 4 , Ti- (OC 9 H 19 ) 4 , VO(OC 8 H 17 ) 3 , Zr(OC 4 H 9 ) 4 , (C 4 H 9 O) 3 Ti-O-Ti.OC 4 H 9 ) 2 -O-Ti(OC 4 H 9 ) 3 , Ti(OC 4 H 9 ) 4 /Zr- (OC 4 H 9 ) 4 , or Ti(OC 2 H 5 ) 2 , and (iii) Al(C 2 H 5 )Cl 2 Al(C 2 H 5 ) 2 Cl or AlCl 3 . |
