摘要： The invention pertains generally to an improved polymer composition which contains at least one liquid polymeric polyphosphite additive containing no alkylphenols. Alkylphenol-free polymeric polyphosphites offer distinct advantages over conventional phosphite technology in polyolefin films. Polymeric polyphosphites offer improved performance in regards to the prevention of color formation during high temperature processing, NOx aging, and gamma irradiation.
摘要翻译： 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液体聚合多亚磷酸酯添加剂。 与聚合物薄膜中的常规亚磷酸盐技术相比，无烷基酚聚合多亚磷酸酯具有明显优势。 聚合多磷酸酯在防止高温加工，NOx老化和γ照射期间的颜色形成方面提供了改进的性能。
