|polyethylene glycol terephthalate;[高分子]聚对苯二甲酸乙二醇酯
聚乙烯对苯二甲酸酯（polyethylene terephthalate，缩写PET）是一种热塑性聚合物，由对苯二甲酸（terephthalic acid）与乙二醇（ethylene glycol）通过酯化反应和缩聚反应合成。该材料具有高机械强度、耐化学腐蚀性和透明性，属于聚酯类高分子化合物。
从化学结构来看，PET的重复单元包含刚性的对苯二甲酸基团与柔性的乙二醇链段交替排列，这种结构特性使其同时具备优异的尺寸稳定性和加工流动性。根据国际纯粹与应用化学联合会（IUPAC）的命名规则，其系统命名为聚（氧乙烯氧对苯二甲酰）。
在工业应用中，PET主要用于制造：
美国食品药品监督管理局（FDA）将其列为食品接触安全材料（21 CFR 177.1630），其玻璃化转变温度约70°C，熔点255-265°C。环境方面，美国国家环境保护局（EPA）数据显示，PET回收率可达29%，属于1号可回收塑料，但自然降解需要超过450年。
Polyethylene Terephthalate（PET） 是聚对苯二甲酸乙二醇酯的英文名称，简称PET或PETE，是一种热塑性聚合物，属于聚酯类材料。以下是详细解释：
