Abstract

Los compuestos de la presente invención son excelentes estabilizadores para los polímeros que contienen enlaces dobles, tales como por ejemplo caucho natural, caucho de estireno-butadieno (SBR), caucho de nitrilo y caucho de cloropreno. Estas sustancias poseen un efecto especial en la estabilización de látices de caucho, látices de SBR. Los materiales de caucho estabilizados con ellos tienen, en comparación con la estabilización conocida por el actual estado de la técnica con autioxidantes fenólicos una estabilidad considerablemente mejorada en las solicitudes termioxidativas y un descoloreamiento mucho más reducido bajo la luz. Además, estos efectos ventajosos se pueden alcanzar ya con una fracción de la cantidad de estabilizadores que generalmente se incorporan en el caucho (aprox. 1-2% en peso).
