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.

Synthetic polymers comprising additive blends with enhanced effect

Polyolefin mouldings which have excellent stability on permanent contact with extracting media comprise, as stabilizers, a selected mixture comprising an organic phosphite or phosphonite and a specially selected group of sterically hindered phenols or a certain group of sterically hindered amines. In addition, a selected three-component mixture comprising a phosphite or phosphonite, a phenolic antioxidant and a certain group of sterically hindered amines is particularly suitable as stabilizer for polyolefin moldings which are in permanent contact with extracting media.

Process for stabilization of polyolefins in permanent contact with extracting media

A process is described for the preparation of olefin polymers by polymerization over a transition metallocene catalyst with the addition of at least one phosphorus(III) compound, sterically hindered amine, sterically hindered phenol or acid scavenger, alone or in combination with one another; the polymers which can be obtained in this way are of outstanding stability.
