    • The invention relates to a composition comprising a modified, random copolyetherester containing a modified, random polybutylene terephthalate copolymer block that is derived from a polyethylene terephthalate component selected from the group consisting of polyethylene terephthalate and polyethylene terephthalate copolymers and combinations thereof; and contains at least one residue derived from the polyethylene terephthalate component; and a polyalkylene oxide copolymer block that is derived from a polyethylene terephthalate component and polyalkylene oxide glycol, and contains polyalkylene oxide and at least one residue derived from the polyethylene terephthalate component. Advantageously, the composition has a modulus of elasticity that is at least 80%, as compared to the modulus of elasticity of a copolyetherester derived from (1) polybutylene terephthalate derived from a monomer component selected from the group consisting of terephthalic acid, isophthalic acid, alkyl esters of terephthalic acid, hydroalkyl esters of terephthalic acid, alkyl esters of isophthalic acid, 1, 4-butanediol, (2) polyalkylene oxide glycol, and (3) combinations thereof. The invention also relates to articles made from the composition, methods of making the composition. The invention also relates to copolyetherester containing: a modified, random polytrimethylene terephthalate copolymer blocks, articles made from the compositions, and methods for making such materials.
    • 本发明涉及一种组合物,其包含改性的无规共聚醚酯,其包含改性的随机聚对苯二甲酸丁二醇酯共聚物嵌段,其衍生自聚对苯二甲酸乙二醇酯组分,所述聚对苯二甲酸乙二醇酯组分选自聚对苯二甲酸乙二醇酯和聚对苯二甲酸乙二醇酯共聚物及其组合; 并含有至少一种衍生自聚对苯二甲酸乙二醇酯组分的残基; 和衍生自聚对苯二甲酸乙二醇酯组分和聚环氧烷二醇的聚环氧烷共聚物嵌段,并含有聚环氧烷和至少一种衍生自聚对苯二甲酸乙二醇酯组分的残基。 有利的是,与来自(1)聚对苯二甲酸丁二醇酯的共聚醚酯的弹性模量相比,组合物的弹性模量为至少80%,所述聚对苯二甲酸丁二醇酯衍生自选自对苯二甲酸,间苯二甲酸, 对苯二甲酸的烷基酯,对苯二甲酸的烷基酯,间苯二甲酸的烷基酯,1,4-丁二醇,(2)聚环氧烷二醇和(3)它们的组合。 本发明还涉及由该组合物制成的制品,以及制备该组合物的方法。 本发明还涉及共聚醚酯,其包含:改性的无规聚对苯二甲酸丙二醇酯共聚物嵌段,由组合物制成的制品,以及制备这些材料的方法。
