Verwendung von Phosphoramino- und Thiophosphoraminoverbindungen als Stabilisatoren

摘要

Organic materials contain as stabiliser against heat, oxygen and/or light 0.01 - 5% of a cpd of formula in which n = 1 or 2, R1 and R2 either form a heterocyclic ring with the N-atom or independently represent a (substd) alkyl or cyclohexyl group or (substd) phenyl group, X and Y independently represent or (substd) phenyl group; n=2 if both X and Y=N The materials which may be stabilised include e.g. paraffin oils, polyolefins, PVC and copolymers.
