    Abstract: A method of making an aliphatic polyester prepolymer, comprising: reacting, alone or in combination with other reactants, a diol with at least a first diacid (or a diester of said first diacid) to produce an aliphatic polyester prepolymer. The first diacid is preferably a trans-beta-hydromuconic acid (HMA). In some embodiments, the diol contains at least one ether linkage. In some embodiments the diol is further reacted with at a second diacid, or a diester of said second diacid, wherein said second diacid is different from said first diacid. Prepolymers produced from such processes and articles formed therefrom are also described.

    Abstract translation: 一种制备脂族聚酯预聚物的方法,其包括:单独或与其它反应物组合使二醇与至少一种第一二酸(或所述第一二酸的二酯)反应以产生脂族聚酯预聚物。 第一种二酸优选是反式-β-水凝胶酸(HMA)。 在一些实施方案中,二醇包含至少一个醚键。 在一些实施方案中,二醇进一步与所述第二二酸的第二二酸或二酯反应,其中所述第二二酸不同于所述第一二酸。 还描述了由这些方法制备的预聚物和由其形成的制品。
