| titleOfInvention | Batch-type continuous polymerization of liquid crystalline polyester |
| abstract | (57) [Summary] [Structure] Liquid crystalline polyester is melt-polymerized in a polymerization can equipped with a raw material inlet or liquid transfer port, a polymer discharge port, a stirrer and a jacket, and the molten polymer is discharged. In the batch type continuous polymerization method in which the same polymer is charged into the same polymerization vessel and the polymerization is repeated, the temperature inside the polymerization vessel is lowered within 1.5 hours after the molten polymer is discharged. (Tc) A batch type continuous polymerization method of a liquid crystalline polyester, which comprises cooling to a temperature of −5 ° C. or lower, and then charging the next raw material. [Effect] Since the liquid crystalline polyester obtained by this method has few foreign matters and no clogging of the die, the yield of pellets is improved. |
