摘要： Hydroquinone-3,4'-biphenyl dicarboxylate polyesters, and methods of making them, are described. The polyesters may be melt processed at a temperature below the thermal decomposition temperature and the isotropic temperature, and may form a liquid crystalline glass phase. The polyesters may be formed by polycondensation of hydroquinone or a hydroquinone derivative with 3,4'-biphenyl dicarboxylic acid.

摘要： Bibenzoate copolyesters are based on (4,4'-biphenyl dicarboxylic acid- co -3,4'-biphenyl dicarboxylic acid) as the diacid component, and on an alicyclic diol compound such as 1,4-cyclohexanedimethanol as a portion of the diol component. Copolyesters are based on 4,4'-biphenyl dicarboxylic acid, and/or 3,4'-biphenyl dicarboxylic acid as the diacid component, and may include a multifunctional acid. Copolymers may optionally have an essentially amorphous morphology, high glass transition temperature, high elongation at break, and/or high melting temperature. A method to make the copolyesters controls the characteristics of the copolyester selected from one or a combination of amorphous morphology or degree of crystallinity, Tg, Tm, tensile modulus, flexural modulus, elongation at break, and so on, by selecting the proportions of the 4,4'-biphenyl dicarboxylic acid or ester producing equivalent thereof, 3,4'-biphenyl dicarboxylic acid or ester producing equivalent thereof, and/or the proportion of the 1,4-cyclohexanedimethanol in the diol component.

摘要： Copolyesters are based on a diacid component containing terephthalate and4,4'-biphenyl dicarboxylate or 3,4'-biphenyl dicarboxylate, and a diol component containing an alkylene diol, e.g., ethylene glycol or NPG, and an alicyclic polyhydroxyl compound, e.g., CHDM. The copolyesters may have a glass transition temperature more than 100°C and mechanical, thermal and/or barrier characteristics at least comparable to some commercially available copolyesters. A method to control the morphology and properties of a copolyester involves contacting diacid and diol components in the presence of a catalyst, selecting proportions of terephthalic and 4,4'-biphenyl dicarboxylic or 3,4'-biphenyl dicarboxylic acids or ester producing equivalents thereof in the diacid component, and selecting the alkylene diol and proportions of the CHDM (or other alicyclic polyhydroxyl compound) and the alkylene diol in the diol component, to obtain the desired morphology and other properties.

摘要： This disclosure relates to methods for production of aromatic esters useful as plasticizers without using esterification catalyst, to the aromatic esters, and to polymer compositions containing the aromatic esters. It also relates to producing aromatic polyesters without using esterification catalyst. The aromatic esters and polyesters can be produced catalyst-free by esterifying carboxylic acids with alcohol(s) at high temperature and high pressure, namely at a temperature from 100°C to 350°C and a pressure ≥ 100 psig, preferably ≥ 600 psig. The aromatic esters and polyesters can also be produced by esterifying without esterification catalyst carboxylic acids with methyl or ethyl alcohol, separating the resulting methyl or ethyl esters from the carboxylic acid and any byproduct impurities, and then transesterifying with or without esterification catalyst the methyl or ethyl esters with alcohols and/or diols.
摘要翻译：本公开涉及生产用作增塑剂而不使用酯化催化剂的芳族酯，芳族酯以及含芳族酯的聚合物组合物的方法。它还涉及不使用酯化催化剂生产芳族聚酯。芳香族酯和聚酯可以通过在高温和高压下，即在100℃至350℃的温度和≥100psig的压力下，优选≥600psig下用醇酯化羧酸来生产无催化剂。芳族酯和聚酯也可以通过用甲酯或乙醇酯化没有酯化催化剂的羧酸来制备，从羧酸和任何副产物杂质中分离得到的甲酯或乙酯，然后用或不用酯化催化剂酯交换甲酯或乙酯与醇和/或二醇的酯。
