| titleOfInvention | Production of heat-resistant polyester |
| abstract | PURPOSE: To obtain the titled polyester of excellent heat resistance, by reacting a polyester with a specified aziridinylphosphine oxide and thereby lowering the content of terminal carboxyl groups. n CONSTITUTION: A polyester of intrinsic viscosity ≥0.50, obtained by polycondensing an aromatic dicarboxylic acid (e.g., terephthalic acid) with a 2W6C glycol (e.g., ethylene glycol) is reacted with 0.2W5wt% aziridinylphosphine oxide of the formula (wherein R 1W4 are each H or a monovalent hydrocarbon group) for at least 3min at a temperature above the melting temperature of the polyester to lower the content of terminal carboxyl groups to 15g-equivalent/10 6 g- polymer or below. n EFFECT: The molecular chains are linked and its degree of polymerization is increased. Therefore, it is possible to obtain a polyester having improved resistance to hydrolysis or aminolysis at high temperatures. n COPYRIGHT: (C)1984,JPO&Japio |
