Abstract

Polímeros sintéticos estabilizados. Contienen, para luchar contra la degradación inducida por la luz, calor u oxidación, una mezcla estabilizadora que contiene (A) un compuesto amínico estéricamente impedido, y (B) dos compuestos diferentes del grupo constituido por una sal orgánica o inorgánica de Zn o de Mg, siendo la relación en peso de los dos compuestos diferentes 1:5 a 5:1, con las salvedades descritas en la descripción. La mezcla estabilizadora se usa para estabilizar polímeros sintéticos sujetos a degradación por la luz, calor u oxidación, particularmente para olefinas.
