Abstract
Système de stabilisation destiné à supprimer le jaunissement des polymères au styrène comprenant un benzotriazole tel que 2-(2'-hydroxy-3',5'-di-tert-amylphényl)benzotriazole, un hydroxybenzocyanurate tel que tris-(3,5-di-tert-butyl-4-hydroxybenzyl)isocyanurate et un produit de condensation d'une N,N'-(2,2,6,6-tétraméthylpipéridyl)alkylènediamine et d'une 6-amino-2,4-dichloro-1,3,5-s-triazine tel que le produit de condensation de N,N'-(2,2,6,6-tétramétylpipéridyl)hexaméthylènediamine et de 6-morpholino-2,4-dichloro-1,3,5-s-triazine. De plus, ce système de stabilisation peut comprendre un thiodipropionate dialkyle et un dialkyldithiocarbamate de zinc.
