1. A process to form a viscosified liquid slurry polymerization additive, the process comprising:
contacting a polymerization additive with a liquid to form a liquid slurry polymerization additive, wherein the polymerization additive comprises an aluminum stearate and at least one other material; and
increasing a viscosity of the liquid slurry polymerization additive by shearing the liquid slurry polymerization additive to form the viscosified liquid slurry polymerization additive, wherein the shearing comprises mixing the liquid slurry polymerization additive with an agitator rotated at a speed within a range of from 750 rpm to 1250 rpm for a time period within a range of from one hour to one week.
