| titleOfInvention | Production of easily slidable polyester |
| abstract | PURPOSE: To obtain an easily slidable polyester excellent in transparency and easy slidability, by reacting terephthalic acid with a glycol, adding a P compound, depolymerizing the mixture and, after adding a Li compound and a Ca compound, polycondensing the reaction mixture. n CONSTITUTION: In producing a polyester by the transesterification (or esterification) and polycondensation from starting materials comprising terephthalic acid or a bifunctional carboxylic acid mixture based thereon, or its esterifiable derivative and ethylene glycol, a gltcol mixture based thereon, or its esterifiable derivative; the transesterification or esterification is performed first, then the prepolymerization is carried out, and then a phosphorus compound is added. An oligomer contained in the formed polyester is depolymerized with a glycol at a temperature higher than the m.p. of the polyester in an inert gas atmosphere. To this are further added both a lithium compound and a calcium compound, and the polycondensation is started and continued to completion. n COPYRIGHT: (C)1984,JPO&Japio |
