| titleOfInvention | Production of polyester |
| abstract | PURPOSE: To produce a polyester excellent in electrostatic cohesion and heat resistance, by reacting terephthalic acid with ethylene glycol in the presence of Ca and/or Mg compounds while adding a P compound in divided portions. n CONSTITUTION: A dicarboxylic acid component based on terephthalic acid or an esterifiable derivative thereof is reacted with a glycol component based on ethylene glycol in the presence of 30W400ppm (in terms of metal atoms) of Ca and/or Mg compounds, 50% or below, based on the total amount to be added, P compound (e.g., phosphoric acid) and, optionally, 30W500ppm (in terms of metal atom) of at least one compound selected from the group consisting of Li, Na, K, Mn, and Zr compounds. When the transesterification reaction or the esterification is completed, the remainder of the P compound is added and the reaction is brought to completion. n COPYRIGHT: (C)1985,JPO&Japio |
