Abstract
In a continuous process for production of polyester polymers, polymer additives are added to the process stream at a point where the polymer is molten by injecting a stable liquid dispersion formed from a liquid polyisobutene and the requisite polymer additives. The process is particularly useful in production of thermally stabilized polyesters wherein a stabilizing amount of a copper complex compound is incorporated therein.
