Stabilisering av polyolefiner i långvarig kontakt med extraherande medier med hjälp av fosfiter eller fosfoniter |
摘要 |
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. |
