A mixture of a polyester or a polyamide, such as poly(ethylene terephthalate) PET, and a suitable stabilizer selected from the group consisting of certain Mannich base compounds, when extrusion compounded exhibits a lower residual acetaldehyde content than does PET or polyamide alone when similarly treated. The invention pertains to any polyester or polyamide used in the manufacture of molded articles, fibers, or films, for instance bottles or containers which are used to store consumer materials, for example food, beverages and water.
一种由聚酯或聚酰胺混合物,例如聚对苯二甲酸乙二酯(PET),以及从某些曼尼希碱化合物组成的适当稳定剂中选择的稳定剂,在挤出混合后的残留乙醛含量比单独处理的PET或聚酰胺低。该发明涉及用于制造模塑品、纤维或薄膜的任何聚酯或聚酰胺,例如用于存储消费者材料的瓶子或容器,例如食品、饮料和水。
