| titleOfInvention | Preparation of aromatic polyester resin |
| abstract | PURPOSE: To obtain an arom. polyester resin with good processability at a low cost by reacting a specified arom. diol, an arom. dibromide and carbon monoxide in the presence of a palladium catalyst and an org. base in an org. solvent. n CONSTITUTION: An arom. diol (A) of formula I (wherein Ar 1 is a divalent arom. group) (e.g., bisphenol A), an arom. dibromide (B) of formula II (wherein Ar 2 is a divalent arom. group) [e.g., bis(4-bromophenyl) ether] and carbon monoxide (C) are reacted together in the presence of a palladium catalyst (e.g., palladium chloride) and an org. base (e.g., tributylamine) in the org. solvent (e.g., dimethylformamide) to obtain with good processability an arom. polyester resin of formula III (wherein n is 10-100). n COPYRIGHT: (C)1990,JPO&Japio |
