Abstract
The dispersion of additives selected from the group consisting of stabilizers, antistatic agents, nucleating agents, biocides and/or flame retardants in synthetic polymers is improved by the addition of at least one polymeric dispersing or solvating agent having amphiphilic properties. Synthetic polymers stabilized in this manner are distinguished by having excellent stability against oxidative, thermal or light-induced degradation.
