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

Claim (Index 47):
A solution olefin polymerization process comprising\n i) adding to one or more continuous stirred tank reactor (CSTR), optionally followed by a tubular reactor, either in series or parallel, a solvent chosen from C 5-12  alkanes, or mixtures thereof, and a procatalyst for polymerization on a delta form MgCl 2  support comprising a Ti 3+  complex of the formula TiCl 3 *[[R 4 ] a [R 5 O] b AlX 3-c ] d  wherein\n a is 0 to 1; \n b is 0 to 1; \n c=a+b; \n d is from 0.33 to 1.0; \n each R 4  and R 5  is independently chosen from C 1-8  alkyl radicals; \n each X is independently chosen from the halogen radicals; \n wherein at least 60% of the total Ti present is in the Ti 3+  oxidation state; \n and further wherein the next steps of the procatalyst formation follow without the need for intervening washing steps;\n ii) adding ethylene, hydrogen and optionally one or more comonomers chosen from C 3-8  comonomers to the reactor; and \n iii) adding an aluminum alkyl activator to the reactor in a molar ratio of about 1 to about 10 relative to the amount of procatalyst.
