Claim 0:
1. A heterogeneous procatalyst comprising:
a titanium species;
a chlorinating agent having a structure A(Cl)x(R1)3-x, where:
A is aluminum or boron;
R1 is a (C1-C30) hydrocarbyl; and
x is 1, 2, or 3; and

a thermally treated magnesium chloride (MgCl2) component, wherein the thermally treated magnesium chloride component comprises a product of thermally treating a magnesium chloride slurry at a temperature of at least 150° C. for at least 30 minutes;
wherein:
a molar ratio of the chlorinating agent to the thermally treated MgCl2 component in the heterogeneous procatalyst is from 3:40 to 14:40; and
a molar ratio of the titanium species to the thermally treated MgCl2 component in the heterogeneous procatalyst is from 0.5:40 to 5:40.
