Abstract
Processes for making and using a viscosified liquid slurry polymerization additive are disclosed herein. The process for making a viscosified liquid slurry polymerization additive comprises contacting a polymerization additive with a liquid to form a liquid slurry polymerization additive, and shearing the liquid slurry polymerization additive to increase its viscosity and thus form the viscosified liquid slurry polymerization additive. The process for using a viscosified liquid slurry polymerization additive comprises contacting, under polymerization conditions, in a reactor system: a catalyst system, one or more monomers, and at least one viscosified liquid slurry polymerization additive.
