    • Described herein is a melt-processable block copolyesterimide comprising the repeating units (I), (II) and (III) and, optionally, a repeating unit (IV), wherein (I) is a repeating unit of formula (I) wherein R is an aliphatic polyether chain and/or a polysiloxane chain; (II) and (III) are repeating units of formulaes (II) and (III) wherein Z is hydrogen, alkyl, alkoxy, aryl, halogen and w is zero or one; and (IV) is a repeating unit of formula (IV), wherein Z' is hydrogen, alkyl, alkoxy, aryl or halogen and the phenylene ring is substituted in m- or p-position. The repeating unit of formula (I) is present in an amount of 5 to 50 mole-%, the repeating unit of formula (II) is present in an amount of 10 to 80 mole-%, the repeating unit of formula (III) is present in an amount of 5 to 50 mole-% and the repeating unit of formula (IV) is present in an amount of 0 to 45 mole-% of the block copolyesterimide. The polymer according to the invention has liquid crystalline properties and it can be used as thermoplastic elastomer component of polymer compounds.
    • 本文描述的是包含重复单元(I),(II)和(III)和任选的重复单元(IV)的可熔融加工的嵌段共聚酯酰亚胺,其中(I)是式(I)的重复单元,其中R 是脂族聚醚链和/或聚硅氧烷链; (II)和(III)是式(II)和(III)的重复单元,其中Z是氢,烷基,烷氧基,芳基,卤素和w是0或1; 和(IV)是式(IV)的重复单元,其中Z'是氢,烷基,烷氧基,芳基或卤素,亚苯基环在取代或取代的位置。 式(I)的重复单元的存在量为5至50摩尔%,式(II)的重复单元的存在量为10至80摩尔%,式(III)的重复单元 以5〜50摩尔%的量存在,式(IV)的重复单元的存在量为嵌段共聚酯酰亚胺的0〜45摩尔%。 根据本发明的聚合物具有液晶性质,并且可以用作聚合物化合物的热塑性弹性体组分。
