Abstract:
1. Polymer composition comprising: a) 10-99.99% by weight of at least one polyolefin, b) up to 50% by weight of a thermoplastic that is not a polyolefin, c) 0.005-1% by weight of per se known polymer additives, d) a fat-soluble iron compound prepared by allowing an iron salt to react with an acidic, organic compound in a process in which a suitable oxidation means ensures that all iron in the final product is present in its highest stable oxidation state at standard conditions; and (e) at least one polybranched organic/inorganic hybrid polymer comprising an inorganic core carrying organic branches that constitute a particle structure characterized in that the particulate polybranched organic/inorganic hybrid polymer is prepared by a sol-gel process, said sol-gel process comprising at least the following steps in chronological sequence;
