The invention relates to stabilizer mixtures which are suited for stabilizing polymers that contain halogen, particularly PVC, whereby said mixtures contain: a) a perchlorate salt, and; b) an alkanolamine of formula (I) or a reaction product consisting of a monofunctional or polyfunctional epoxide and ammonia or of a monofunctional or polyfunctional dialkyl (aryl)amine or monoalkyl (aryl)amine.
L'invention concerne des mélanges d'agents stabilisants contenant au moins a) un sel de perchlorate et b) une alcanolamine de formule (I) ou un produit de réaction à base d'un époxyde mono- ou polyfonctionnel et d'ammoniac ou d'une dialkyl(aryl)- ou monoalkyl(aryl)amine mono- ou polyfonctionnelle. Ces agents stabilisants s'utilisent pour stabiliser des polymères à base d'halogène, notamment du PVC.
