    • This invention relates to adhesion agents and compatibility agents, respectively, on the basis of partially crystalline, high-molecular block (co)polyester amides, produced by direct esterification of carboxyl-terminated or hydroxycarboxyl-terminated polyamide precondensates and hydroxyl-terminated or hydroxycarboxyl-terminated polyester segments, characterized in that the block (co)polyester amides form two crystalline phases and comprise as segments(A) at least one polyamide or copolyamide block having a uniform number average molar mass of at least 1000 g/mole,(B) at least one aromatic polyester and/or copolyester block having a uniform number average molar mass of at least 1000 g/mole, and(C) at least one further diol component of the general structureHO--R--OH,wherein R is selected from the group consisting of aliphatic or partially aromatic (co)polyesters, aliphatic polyethers, aliphatic (co)polyester amides, polycarbonates or aliphatic or aromatic hydrocarbons.Furthermore, this invention concerns a process for the production of the above-mentioned block (co)polyester amide molding compounds as well as various possible uses.
    • 本发明分别基于通过羧基封端或羟基羧基封端的聚酰胺预缩合物和羟基封端的或羟基羧基封端的直链酯化产生的部分结晶的高分子嵌段(共)聚酯酰胺, 封端的聚酯片段,其特征在于嵌段(共)聚酰胺形成两个结晶相,并且包含至少一个平均摩尔质量至少为1000g / mol的聚酰胺或共聚酰胺嵌段作为链段(A),(B) 至少一种芳族聚酯和/或共聚酯嵌段具有至少1000g / mol的均匀数均摩尔质量,和(C)至少一种另外的一般结构HO-R-OH的二醇组分,其中R选自 由脂族或部分芳族(共)聚酯,脂族聚醚,脂族(共)聚酯酰胺,聚碳酸酯或脂族或芳族烃组成的组。 此外,本发明涉及制备上述嵌段(共)聚酯酰胺模塑料的方法以及各种可能的用途。
