Polyisophthalates, for example, poly(ethyleneisophtha- late), or copolymers thereof, have low glass transition temperatures, even lower than poly(ethylene terephthalate). Unexpectedly, such polyisophthalates have very good barrier properties with regard to oxygen and carbon dioxide penetration. The polyisophthalates can be utilized as packaging materials, for example as films or containers such as bottles for beverages such as intoxicating beverages such as beer, and the like.
聚异酞酸酯,例如聚(乙烯-异酞酸酯)或其共聚物的玻璃化温度较低,甚至低于聚(对苯二甲酸乙二醇酯)。令人意想不到的是,这种聚异酞酸酯对氧气和二氧化碳的渗透具有很好的阻隔性能。聚间苯二甲酸盐可用作包装材料,例如薄膜或容器,如饮料瓶,如啤酒等烈性饮料。
