The invention relates to a process for the preparation of thermally and oxidatively stable olefin polymers, wherein the addition of sterically hindered amines in combination with a phosphorus-III ester for the polymerization of olefins on spherical Ziegler-Natta catalysts causes a thermal-oxidative stabilization of the polymers formed , It is also possible to add phenolic antioxidants. {Olefin polymer production; thermally oxidative stable; Additional amine, sterically hindered; Phosphorus-III ester additive; Antioxidants, phenolic; Ziegler-Natta catalysts} |
