Claim 15:
16. A process of preparing a heterogeneous procatalyst, the process comprising contacting components (1) and (2) without further chlorination, wherein:
component (1) is a preformed heterogeneous procatalyst comprising:
a titanium species; and
a MgCl2 support; and

component (2) is a metal-ligand complex having a structural formula (L)nM(Y)m(XR2)b, where:
M is a metal cation;
each L is a neutral ligand or (═O);
each Y is a halide or (C1-C20)alkyl;
each XR2 is an anionic ligand in which X is a heteroatom or a heteroatom-containing functional group and R2 is (C1-C20)hydrocarbyl or (C1-C20)heterohydrocarbyl;
n is 0, 1, or 2;
m is 0, 1, 2, 3, or 4;
b is 1, 2, 3, 4, 5, or 6; and
the metal-ligand complex is overall charge neutral;

wherein the metal-ligand complex comprises at least one of vanadium(V) oxytripropoxide, vanadium(V) oxytributoxide, vanadium(V) oxytriisopropoxide, titanium(IV) isopropoxide, or combinations thereof.
