Abstract: The present invention relates to a polymer composition comprising a heterophasic propylene copolymer, a mineral filler and a light stabilizer comprising a fatty acid derivative and a benzoate derivative. The polymer composition according to the present invention is applicable for automotive articles whereupon the undesired effect of the final odor is reduced significantly compared to automotive articles comprising conventional light stabilizers.
Abstract translation: 本发明涉及包含异相丙烯共聚物，矿物填料和包含脂肪酸衍生物和苯甲酸酯衍生物的光稳定剂的聚合物组合物。 根据本发明的聚合物组合物可用于汽车制品，因此与包含常规光稳定剂的汽车制品相比，最终气味的不期望的影响显着降低。
