  摘要：

  合成了三种新的四氧亚环聚芳烃，这些化合物包含两个分别位于4,4'位的联苯核，通过氧聚甲烷氧桥连接，例如1,5,18,22-四氧[5.0.5.0]亚环聚芳烃I3、1,6,19,24-四氧[6.0.6.0]亚环聚芳烃I4和1,7,20,26-四氧[7.0.7.0]亚环聚芳烃I5。对这些亚环聚芳烃的紫外光、红外线和核磁共振谱与相应的开链化合物IV3进行了比较。

  The present invention provide a liquid crystalline polyester that can be used in production of a molded article having sufficient mechanical strengths in which the melted liquid crystalline polyester has sufficient fluidity in thin-walled portions when the thin-walled molded article is manufactured, and to provide a method for producing the liquid crystalline polyester. A liquid crystalline polyester obtained by copolymerizing 4-acyloxybenzoic acids (I) and 2-acyloxy-6-naphthoic acids (II) in the presence of an imidazole (V) can be used in production of a molded article in which the melted liquid crystalline polyester has sufficient fluidity in thin-walled portions when the thin-walled molded article is manufactured, and which has sufficient mechanical strengths as well, thereby completing the present invention. Further, a liquid crystalline polyester obtained by copolymerizing 4-acyloxybenzoic acids (I), 2-acyloxy-6-naphthoic acids (II), 4,4′-diacyloxybiphenyls (III) and phthalic acids (IV) in the presence of an imidazole (V) can be used in production of a molded article in which the melted liquid crystalline polyester has sufficient fluidity in thin-walled portions when the thin-walled molded article is manufactured, and which has sufficient mechanical strengths as well, thereby completing the present invention.

  本发明提供一种液态结晶聚酯，该液态结晶聚酯可用于生产具有足够机械强度的模塑制品，在生产薄壁模塑制品时，熔化的液态结晶聚酯在薄壁部分具有足够的流动性，并提供一种生产该液态结晶聚酯的方法。4-acyloxybenzoic acids (I) 和 2-acyloxy-6-naphthoic acids (II) 在咪唑 (V) 存在下共聚得到的液态结晶聚酯可用于生产模塑制品，其中熔化的液态结晶聚酯在制造薄壁模塑制品时在薄壁部分具有足够的流动性，并且具有足够的机械强度，从而完成了本发明。此外，通过共聚 4-acyloxybenzoic acids (I)、2-acyloxy-6-naphthoic acids (II)、4、4′-二acyloxybiphenyls（III）和邻苯二甲酸（IV）在咪唑（V）存在下共聚得到的液态结晶聚酯可用于生产模塑制品，在生产薄壁模塑制品时，熔化的液态结晶聚酯在薄壁部分具有足够的流动性，并且具有足够的机械强度，从而完成了本发明。
