    • A single reactor process for formation of block copolymers comprising aromatic ester mesogenic units containing flexible alkane spacers and polyester flexible coil units in the main chain thereof which comprises reacting an (alpha), (omega)-bis(hydroxybenzoyloxy) alkane monomer with an aromatic acid chloride in the presence of a functionalized flexible coil oligomer under temperature conditions in which an acid chloride-terminated bis(hydroxyalkyl terephthalate) oligomer was first formed at a first, lower temperature and the block copolymer was then formed at a second, higher temperature by reacting this oligomer with the functionalized flexible coil oligomer.
    • 用于形成嵌段共聚物的单反应器方法,其包括在其主链中含有柔性烷烃间隔物和聚酯柔性线圈单元的芳族酯介晶单元,其包括使(α),(ω) - 双(羟基苯甲酰氧基)烷烃单体与芳族酸反应 氯化物在官能化的柔性线圈低聚物的存在下,在其中首先在第一个较低温度下首先形成酰氯封端的双(羟烷基对苯二甲酸酯)低聚物的温度条件下,然后通过使第二较高温度下的 该低聚物具有功能化的柔性线圈低聚物。
