Abstract
1306001 Olefin polymerization catalyst FARBWERKE HOECHST AG 4 May 1971 [5 May 1970] 12891/71 Heading C3P A catalyst for the polymerization of α-olefins comprises (A) a product obtained by reacting together magnesium ethoxide, titanium tetraisopropoxide and titanium tetrachloride in the molar ratio 0À5-5 : 1À0-1À9 : 2À1-3À0, the reaction being carried out at 20-120‹ C. in an inert diluent, and (B) an organometallic compound of a metal of Groups Ia, IIa or IIIb, preferably an organoaluminium compound. In the preparation of component (A) an aluminium alkoxide, e.g. the isopropoxide, may also be present in an amount of 0À1 to 1 mole per mole of magnesium ethoxide. Components (A) and (B) may be mixed in the presence of the monomer or they may be pre-mixed, the resulting catalyst being washed and then activated with additional organometallic compound, if desired. The catalyst gives such high yields of polymer that catalyst removal is unnecessary. It is particularly suited to the polymerization of ethylene, optionally with up to 10% by wt. of another α-olefin; homopolymerization of ethylene and copolymerization with hexene-1 or propylene are exemplified. Polymerizations in solution or in the gas phase (the catalyst being dispersed or preformed polymer) are described. Exemplified as component (B) are AlEt 3 and Al(i-Bu) 3 ; for gas-phase polymerizations preformed catalysts were activated with Al(i-Bu) 3 or AlEt 2 H.
