| titleOfInvention | Manufacture of aromatic polyester |
| abstract | PURPOSE: To obtain a high polymerization degree aromatic polyester of outstanding mechanical properties with high solvent and heat resistance, by interfacial polymerization at specified temperatures, between a specific organic solvent solution of acid chloride and an alkaline aqueous solution of specific bisphenol. n CONSTITUTION: The objective polyester can be obtained by interfacial polycondensation between (A) 1W40wt% terephthalic and/or isophthalic acid dichloride organic solvent solution (said solvent is a 1W10C halogenated hydrocarbon, its boiling point T being ≥35°C; pref. methylene chloride, chloroform) and (B) an alkaline aqueous solution of a bisphenol of formula (R 1 , R 2 , R 3 and R 4 are each H, halogen, 1W8C alkyl, etc.) [pref. bis(4-hydroxyphenyl)sulfone, etc.] with a concentration 1W30wt%, in such amounts as to be 0.7W1.5mol of the bisphenol per mole of the dicarboxylic acid component, at a temperature between (T- 15)°C and (T+15)°C. n COPYRIGHT: (C)1986,JPO&Japio |
