| titleOfInvention | Preparation of polyester |
| abstract | PURPOSE: To obtain a polyester capable of being fibers having good color and feeling and transparent films having good slipperiness, by adding a specific phosphorus compound, alkali (earth) metal compound and ammonium compound to a polyester reaction system. n CONSTITUTION: A bifunctional carboxylic acid consisting essentially of terephthalic acid is reacted with an alkylene glycol. In the process, 0.1W5mol%, based on the above-mentioned carboxylic acid component, phosphorus compound expressed by the formula (R is H or monofunctional organic group; X is OH, OR' or monofunctional organic group; R' is monofunctional organic group; Q is metal, H or monofunctional organic group; n is 1 or 0) and 0.001W0.5mol% (in an amount to give the total of equivalents of the above-mentioned phosphorus compound and the metal 2W3.2 times of the number of phosphorus compound mol) ammonium compound expressed by the formula [NH 4 ] + A - (A is anion residue) are added to the polyester reaction system to give the aimed polyester containing uniformly dispersed insoluble fine particles. n COPYRIGHT: (C)1986,JPO&Japio |
