Beschreibung
Zusammenfassung:	Polyolefin compositions comprising i) a polyolefin, ii) one or more phosphorus- containing benzofuranone compounds and iii) one or more acid scavengers are provided excellent protection against discoloration and enhanced thermal stability during melt processing as exhibited by improved retention of molecular weight and maintenance of polymer molecular architecture. Composiciones de poliolefina que comprenden i) una poliolefina, ii) uno o más compuestos de benzofuranona que contienen fósforo y iii) uno o más barredores de ácido que proporcionan excelente protección contra la decoloración y estabilidad térmica mejorada durante el procesamiento por fusión como se exhibe mediante una retención mejorada del peso molecular y el mantenimiento de la arquitectura molecular polimérica.
