Abstract

The invention relates to a process for process for stabilizing polymers by addition of phenolic antioxidants in the form of a concentrated fluid, which comprises cooling, dosing in suitable containers and storing the fluid under the exclusion of oxygen and light, optionally remelting and adding the fluid under the optional addition of further polymer additives to the polymer to be stabilized.
