Abstract
Des compositions de polymères comprennent un copolymère greffé ayant un substrat caoutchouteux pouvant être greffé, contenant un composant monomère formant un caoutchouc diénique, et une partie supérieure (strate supérieure) d'un interpolymère se composant au moins principalement d'un hydrocarbure aromatique monovinylidénique et d'un nitrile ou d'un ester à insutaration éthylénique, et une quantité peu importante, suffisante pour conférer au polymère une stabilité thermique améliorée, d'un mélange de phosphites de tris-(alkylphényle) où le groupe alkyle contient 1-12 atomes de carbone, au moins environ 85 % d'une des positions ortho dans chaque groupe phényle sont substitués par des groupes alkyles ayant 3-12 atomes de carbone, et au moins environ 85 % des positions para dans chaque groupe phényle sont non substitués ou substitués par des groupes méthyles; 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 certaines compositions de copolymères greffés, spécialement dans des compositions de résines d'ABS.
