| titleOfInvention | Production of high-polymerization degree polyester |
| abstract | PURPOSE: To obtain a high-polymerization degree, heat-resistant polyester reduced in the content of terminal carboxyl groups, by reacting a linear saturated polyester with a bisoxazoline compound and a monocarbodiimide compound in a molten state. n CONSTITUTION: A linear saturated polyester in a molten state is reacted with a molten mixture comprising 0.1W5wt% bisoxazoline compound and 0.1W5wt% monocarbodiimide. A representative example of the polyester is polyethylene terephthalate. In the formation of the molten mixture comprising the bisoxazoline compound and the monocarbodiimide compound, a method in which the compounds are first mixed together and then molten is preferable for inhibiting their decomposition. The reaction between both of the melts is carried out over a period of at least 3min at a temperature ≥ the melting temperatures of the compounds after the intrinsic viscosity of the polyester has reached 0.50. n COPYRIGHT: (C)1986,JPO&Japio |
