  A process for producing an aromatic polyester having an increased degree of polymerization, which comprises reacting a substantially linear, fiber forming aromatic polyester containing terminal carboxyl groups and having an aromatic dicarboxylic acid as a main acid component at an elevated temperature with a bis-cyclic imino ether compound of the formula (I) such as 2,2'-bis(2-oxazoline), 2,2'--bis(5,6-dihydro-4H-1,3-oxazine) thereby bonding the molecular chains of the aromatic polyester to each other by the terminal carboxyl groups thereof to rapidly form said aromatic polyester having and increased degree of polymerization. Said reaction can be carried out under atmospheric or elevated pressure. According to the process, an aromatic polyester having a low terminal carboxyl concentration and an increased degree of polymerization can be obtained. n =0 or 1; X1 and X2 typically are -CH2-CH2- or -CH2-CH2-CH2-: R1 and R2 typically are hydrogen or a monovalent hydrocarbon group; D typically is a divalent hydrocarbon group, e.g. ethylene, propylene, butylene.

  一种提高聚合度的芳香族聚酯的生产工艺，包括在高温下将含有末端羧基并以芳香族二羧酸为主要酸组分的基本线性、可形成纤维的芳香族聚酯与式 (I) 的双环亚胺醚化合物（如 2、2'-双（2-噁唑啉）、2,2'-双（5,6-二氢-4H-1,3-噁嗪），从而使芳香族聚酯的分子链通过其末端羧基相互键合，快速形成聚合度更高的芳香族聚酯。 所述反应可在常压或高压下进行。 根据该工艺，可以获得具有低端羧基浓度和更高聚合度的芳香族聚酯。 n =0 或 1； X1 和 X2 通常为-CH2-CH2-或-CH2-CH2-CH2-： R1 和 R2 通常是氢或一价烃基； D 通常是二价烃基，如乙烯、丙烯、丁烯。

  The present disclosure provides a method for preparing a triblock copolymer, and a triblock copolymer including a poly(3-hydroxypropionate) block and a polylactide block bonded to both ends of the poly(3-hydroxypropionate) block, respectively. Further, the present disclosure relates to a method for preparing a triblock copolymer including subjecting a lactide monomer to a ring-opening polymerization in the presence of a poly(3-hydroxypropionate) initiator having hydroxy groups at both ends to prepare a triblock copolymer.
