A non-volatile, acid acceptor which is soluble in polyolefins is added to a film grade polyolefin resin composition to prevent gel streaking/pinstriping or corrosion during film extrusion processes. The acid acceptor has a molecular weight greater than 180 with less than 5% by weight volatiles at 180°C as measured by a thermal evolution analysis.
在薄膜级聚烯烃
树脂组合物中加入一种可溶于聚烯烃的非挥发性酸接受体,以防止在薄膜挤压过程中产生凝胶条纹/细条纹或腐蚀。 根据热演化分析法的测定,这种酸接受体的分子量大于 180,在 180°C 时挥发物的重量比小于 5%。
