| 1. A catalyst composition comprising:
a catalyst compound selected from the group consisting of Group 4 metal complexes containing one or more ligands that are
π-bonded to the transition metal, and metal complexes of the formula,
 wherein
R1 is selected from alkyl, cycloalkyl, heteroalkyl, cycloheteroalkyl, aryl, and inertly substituted derivatives thereof containing
from 1 to 30 atoms not counting hydrogen,
T is a divalent bridging group of from 1 to 20 atoms not counting hydrogen,
R2 is a C6-20 heteroaryl group containing Lewis base functionality,
M is the Group 4 metal,
Xe is an anionic, neutral or dianionic ligand group,
x is a number from 0 to 5 indicating the number of such Xe groups, and
bonds, optional bonds and electron donative interactions are represented by lines, dotted lines and arrows respectively; and
an activator capable of converting said catalyst compound into an active catalyst for addition polymerization;
optionally a carrier;
optionally a liquid diluent, and
a hydroxycarboxylate metal salt additive corresponding to the formula:
 wherein Re and Rf independently each occurrence are hydrogen, halogen, or C16 alkyl.
