生物基聚对苯二甲酸乙二醇酯聚合物及制备其的方法
摘要：
一种生物基聚对苯二甲酸乙二醇酯聚合物，其包括约25到约75重量百分比的对苯二甲酸酯组分和约20到约50重量百分比的二醇组分，其中至少约1重量百分比的对苯二甲酸酯和/或二醇组分中的至少一种源自至少一种生物基材料。一种生产生物基聚对苯二甲酸乙二醇酯聚合物的方法，所述方法包括获得包括乙二醇的二醇组分；获得包括对苯二甲酸的对苯二甲酸酯组分，其中二醇组分和/或二醇组分中的至少一种源自至少一种生物基材料；以及使二醇组分和对苯二甲酸酯组分反应以形成生物基聚对苯二甲酸乙二醇酯聚合物，所述生物基聚对苯二甲酸乙二醇酯聚合物包括约25到约75重量百分比的对苯二甲酸酯组分和约20到约50重量百分比的二醇组分。
摘要（英）：

A bio-based polyethylene terephthalate polymer comprising from about 25 to about 75 weight percent of a terephthalate component and from about 20 to about 50 weight percent of a diol component, wherein at least about one weight percent of at least one of the terephthalate and/or the diol component is derived from at least one bio-based material. A method of producing a bio-based polyethylene terephthalate polymer comprising obtaining a diol component comprising ethylene glycol, obtaining a terephthalate component comprising terephthalic acid, wherein at least one of the diol component and/or the diol component is derived from at least one bio -based material, and reacting the diol component and the terephthalate component to form a bio-based polyethylene terephthalate polymer comprising from about 25 to about 75 weight percent of the terephthalate component and from about 20 to about 50 weight percent of the diol component.
