Abstract

On prévoit des phosphites de triaryle stables vis-à-vis de l'hydrolyse, qu'on incorpore dans des compositions de polymères d'oléfines; les phosphites de tris-(o-alkylphényle) sont plus stables vis-à-vis de l'hydrolyse que les phosphites de tris-(p-alkylphényle) et ceci les rend plus utiles comme additifs de stabilisation thermique dans des compositions de polymères d'oléfines, spécialement dans des compositions de polypropylène; les groupes alkyles dans ces phosphites sont des groupes alkyles à poids moléculaire supérieur, c'est-à-dire ceux ayant 8-12 atomes de carbone.
