CERIUM-STABILIZED POLYAMIDES AND PROCESSES FOR MAKING SAME

A heat-stabilized polyamide composition comprising from 25 wt% to 90 wt%% of an amide polymer from 0.01 wt% to 10 wt% of a cerium-based heat stabilizer, a second heat stabilizer, a halide additive, and less than 0.3 wt% of a stearate additive. A weight ratio of halide additive to stearate additive i...

Beschreibung
Zusammenfassung:	A heat-stabilized polyamide composition comprising from 25 wt% to 90 wt%% of an amide polymer from 0.01 wt% to 10 wt% of a cerium-based heat stabilizer, a second heat stabilizer, a halide additive, and less than 0.3 wt% of a stearate additive. A weight ratio of halide additive to stearate additive is less than 45Ø L'invention concerne une composition de polyamide stabilisée à la chaleur comprenant de 25% en poids à 90% en poids d'un polymère amide de 0,01% en poids à 10% en poids d'un stabilisant thermique à base de cérium, un second stabilisant thermique, un additif d'halogénure et moins de 0,3% en poids d'un additif de stéarate. Un rapport pondéral entre l'additif d'halogénure et l'additif de stéarate est inférieur à 45,0.
