Patent

CA 2497368

The invention describes novel mixtures comprising i) a processing stabilizer selected from the group consisting of hydroxylamine stabilizers, nitrone stabilizers, benzofuran-2-one stabilizers and/or a compound of the formula I wherein R2 is C7-C3oalkyl, R3 is C1-C3oalkyl, and ii) an antistatic agent selected from the group consisting of an ethoxylated amine and/or an ethoxylated amide, as stabilizers for protecting organic materials, in particular synthetic polymers, against oxidative, thermal or light~induced degradation.

L'invention concerne de nouveaux mélanges comprenant i) un stabilisateur de traitement sélectionné dans le groupe renfermant des stabilisateurs d'hydroxylamine, de nitrone, de benzofuran-2-one et/ou un composé de formule I dans laquelle R¿1 ?désigne la formule (II), R¿2? représente un alkyle en C¿7?-C¿3o? et R¿3? désigne un alkyle en C¿1?-C¿3o?, et ii) un agent antistatique sélectionné dans le groupe renfermant une amine éthoxylée et/ou un amide éthoxylé, utilisés comme stabilisateurs permettant de protéger des matières organiques, notamment des polymères synthétiques, contre une dégradation oxydante, thermique ou induite par la lumière.
