Abstract
PURPOSE: To obtain an aromatic polyester having improved quality without causing coloring and deterioration, by making a polyalkylene terephthalate exist in a specific ratio in the polymerization of a totally aromatic polyester, by carrying out the polymerization through bulk polymerization free from a solvent.
CONSTITUTION: (A) When a totally aromatic polyester shown by the formula (X is 1W4C alkyl, -O-, -SO2-, -S-, -CO-; m and n are 0 or 1; d/e is 1/1W10/1; e/f is 9/10W10/9; with the proviso that the substituent groups of the aromatic ring are in para or meta positions to each other), is polymerized, (B) a polyalkylene terephthalate is made to exist in an amount to give 5W20wt% based on the final formed polymer of the polyalkylene terephthalate in the polymerization system and the polymerization is carried out through solventless bulk polymerization, to give the desired polyester.
