ABSTRACT:
A method wherein polymer stabilizers are suspended in a liquid carrier through the use of rheology agents so that a slurry is formed. The slurry can be stored with little or no setting of the stabilizers until needed and then transferred and applied to a polymer such as a thermoplastic polymer. Inasmuch as the slurry is often thixotropic, it can be readily transferred as upon the application of a pumping force thereto. Typically, the polymer can be treated upon the manufacture thereof or immediately thereafter. Polymers so treated have improved storage and processing stablity. Moreover, the stability of the final product is improved.
