    • The invention relates to a composition comprising a modified, random copolyetherester containing a modified, random polytrimethylene 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 contains polyalkylene oxide and at least one residue derived from the polyethylene terephthalate component. 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) polytrimethylene terephthalate derived from a monomer component selected from the group consisting of terephthalic acid, isophthalic acid, alkyl esters of terephthalic acid, hydroxyalkyl esters of terephthalic acid, alkyl esters of isophthalic acid, 1,3-propane diol, (2) polyalkylene oxide glycol, and (3) combinations thereof.
    • 本发明涉及一种组合物,其包含改性的无规共聚醚酯,其含有由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组成的组中的聚对苯二甲酸乙二醇酯组分衍生的改性的无规聚对苯二甲酸丙二醇酯共聚物嵌段; 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的聚环氧烷共聚物嵌段。 该组合物的弹性模量与源自(1)选自对苯二甲酸,间苯二甲酸,烷基酯的单体组分的(1)聚对苯二甲酸丙二醇酯的共聚醚酯的弹性模量相比,至少为80% 的对苯二甲酸,对苯二甲酸的羟烷基酯,间苯二甲酸的烷基酯,1,3-丙二醇,(2)聚环氧烷二醇,和(3)它们的组合。
