| description | The present application relates to an additive system comprising an antioxidant and glyceryl stearate for improving the color of polyethylene resins. Polymer compositions containing an ethylene polymer, 50 to 1500 ppm by weight of glyceryl stearate, and 250 to 7500 ppm by weight of an antioxidant selected from the group consisting of phenolic antioxidants, phosphite antioxidants, thioester antioxidants, or any combination thereof are described. These polymer compositions have an improved initial color, an improved color after long-term aging, or an improved color after multi-pass extrusion process.
本申请涉及用于改善聚乙烯树脂的颜色的含有抗氧化剂和硬脂酸甘油酯的添加剂体系。描述了含有乙烯聚合物、以重量计50-1500ppm的硬脂酸甘油酯和以重量计250-7500ppm的抗氧化剂的聚合物组合物，所述抗氧化剂选自酚类抗氧化剂、亚磷酸酯抗氧化剂、硫酯抗氧化剂或其任何组合。这些聚合物组合物具有改善的初始颜色、改善的长期老化后颜色或改善的多道次挤压加工后颜色。 |
