    Abstract: The invention pertains generally to an improved polymer composition which contains at least one polymeric polyphosphite or copolymeric polyphosphite additive containing no alkylphenols. Alkylphenol-free polymeric polyphosphites offer distinct advantages over conventional phosphite technology in rubbers and rubber compounds. Polymeric polyphosphites offer improved performance in regards to the prevention of color formation during high temperature processing and NOx aging.

    Abstract translation: 本发明一般涉及一种改进的聚合物组合物,其包含至少一种不含烷基酚的聚亚磷酸酯或共聚多磷酸酯添加剂。 不含烷基酚的聚合多磷酸酯与橡胶和橡胶化合物中的常规亚磷酸盐技术相比具有明显的优点。 聚合多磷酸酯在高温加工和NOx老化过程中提高了防止颜色形成的性能。
