Phosphazene Derivatives and Use of Same as Stabilizers for Oils and Greases Based on Perfluoropolyethers |
摘要 |
New phosphazene derivatives, fully substituted by aromatic groups and perfluoropolyethereal chains, are utilized as stabilizers for oils and greases based on perfluoropolyethers. Such derivatives inhibit the degradation process affecting the perfluoropolyethereal chains when these are subjected to high temperatures in an oxidizing atmosphere and in the presence of metals, such as for example aluminium, titanium, vanadium and their alloys, or steels. |
