摘要： A mixture of a polyester, such as poly(ethylene terephthalate) PET, and a second polymer which is poly(vinyl alcohol) or an ethylene/vinyl alcohol copolymer when extrusion compounded exhibits a lower residual acetaldehyde content than does PET alone when similarly treated. The invention pertains to any polyester used in the manufacture of bottles or containers which in turn are used to store consumer materials, especially food, beverages and most especially water.
摘要翻译：当进行挤出复合时，聚酯（例如聚对苯二甲酸乙二醇酯）PET和聚（乙烯醇）的第二聚合物或乙烯/乙烯醇共聚物的混合物在类似处理时表现出比单独的PET更低的残留乙醛含量。本发明涉及用于制造瓶子或容器的任何聚酯，其又用于储存消费材料，特别是食品，饮料，特别是水。
