| titleOfInvention | Aromatic copolyester |
| abstract | PURPOSE: To obtain the title copolyester which is thermotropic and is excellent in strength and dimensional stability by reacting desirably an aromatic hydroxycarboxylic acid (derivative) with a p-hydroxyphenylpropionic acid (derivative) to form a polymer of a specified composition. n CONSTITUTION: Desirably an aromatic hydroxycarboxylic acid (derivative) (e.g. p-hydroxybenzoic acid) is reacted with p-hydroxyphenylpropionic acid (derivative) and an active esterifying agent in a specified ratio to obtain the title copolyester composed of recurring units of formulas I and II (wherein Ar is a 6-18C bivalent aromatic ring; and R is H, an alkyl, an alkoxy, a phenyl or a halogen), containing 10-90mol%, based on the total, units of formula I and 90-10mol%, based on the total, units of formula II and having a melt viscosity of 10-100000P as measured at (flow initiation temperature +20°C) to 400°C and a shear rate of 10 3 /sec. n COPYRIGHT: (C)1990,JPO&Japio |
