Abstract:
The various embodiments of the invention provide, a magnesium titanium polymerization procatalyst, methods for making and using the same.

Claim (Index 38):
A process to prepare an olefin polymerization procatalyst comprising a Ti 3+  complex, said process comprising:\n a) forming a delta form MgCl 2  species by combining \n i) a Mg compound chosen from butylethyl magnesium (BEM), dibutyl magnesium, and butyloctyl magnesium (BOM), in cyclohexane, \n and\n ii) reactive organic chloride or HCl; \n wherein the mole ratio of added Cl and Mg is from 2.15 to 2.5;\n b) adding to said delta form MgCl 2  species prepared in step a), an aluminum alkyl halide of the formula R 1 x AlX 3-x  first, a tetravalent titanium compound second, followed by an alkyl aluminum alkoxide of the formula R 4 y AlOR 5 3-y , wherein the Al/Ti molar ratio when measuring Al supplied from R 1 x AlX 3-x  only is from about 0.7 to about 2 and the Al/Ti molar ratio when measuring Al supplied from R 4 y AlOR 5 3-y  is from about 1 to about 1.7; \n and further wherein\n the Mg/Ti molar ratio is from about 5 to about 10; \n x is 1 or 2; \n y is 1 or 2; \n each R 1  is independently chosen from C 1-8  alkyl radicals; \n the tetravalent titanium compound is chosen from TiR 2 X 3 , Ti(OR 3 )X 3 , TiX 4 , and mixtures thereof; \n each X is independently chosen from the halogen radicals; and \n each R 2  is independently chosen from C 1-8  alkyl radicals and benzyl; \n each R 3 , R 4  and R 5  are independently chosen from C 1-8  alkyl radicals \n wherein the process used to prepare the delta form MgCl 2  species allows for the next steps of the procatalyst formation to follow without the need for intervening washing steps.
