    摘要： A thermotropic polyesterimide, in which the liquid-crystalline phase is of nematic structure within a useful temperature range, consists of units of formula:

    the units being in the following ratios:

    a/(b + c) = 1
    c/b = 0 - 50/50, and preferably c/b

    The polyesterimide of the present invention possesses self-reinforcement characteristics, or reinforcement characteristics for traditional thermoplastic materials.

    摘要： A thermotropic copolyester, showing a liquid-­crystalline structure of nematic type within a desired temperature range, contains umits deriving from:

    (a) a saturated bicarboxy aliphatic acid;
    (b) 4,4′-di-hydroxy-biphenyl;
    (c) 4-hydroxybenzoic acid; and
    (d) 4-hydroxy-benzoic acid bearing an alkyl substituent or a halogen atom bonded to the aromatic ring.

    Such a copolyester constitutes a material endowed with self-reinforcing characteristics, originating, through the usual transformation processes by injection or by extrusion techniques, marked molecular orientations, which supply the manufactured articles with high stiffness characteristics.
    Said material can be also used as a reinforcing agent when is mixed, by means fo the usual techniques, with the traditional thermoplastic polymers.

    摘要： A thermotropic copolyesteramide, with a nematic structure of the liquid crystalline phase within a desired temperature range of the mesophase, contains metered amounts of units derived from: (a) a saturated aliphatic -dicarboxylic acid; (b) 4,4'-dihydroxydiphenyl; (c) 4-hydroxybenzoic acid and (d) 4-aminobenzoic acid or (d') 4-aminophenol. This thermotropic copolyesteramide, produced by the copolymerization of monomers in the molten state, is a material with self-reinforcing characteristics capable of yielding, by normal injection or extrusion processes, remarkable molecular orientations which impart a high rigidity to the manufactured products.
    The copolyesteramide may be used as a reinforcement material for traditional thermoplastic polymers, by usual techniques.

    摘要翻译： 具有在中间相的期望温度范围内的液晶相的向列结构的热致共聚酯酰胺含有计量量的衍生自以下的单元：（a）饱和脂族 - 二羧酸; （b）4,4'-二羟基联苯; （c）4-羟基苯甲酸和（d）4-氨基苯甲酸或（d'）4-氨基苯酚。 这种通过熔融状态下的单体共聚生产的热致共聚酯酰胺是一种具有自增强特性的材料，通过正常的注射或挤出工艺，该材料能够产生显着的分子取向，这赋予所制造的产品高刚性。 通过常规技术，共聚酯酰胺可用作传统热塑性聚合物的增强材料。
