| titleOfInvention | Use of a germanium-containing polycondensation catalyst in the preparation of polyethylene terephthalate |
| abstract | A PROCESS FOR THE PREPARATION OF POLYETHYLENE TEREPHTHALATE BY THE POLYCONDENSATION OF OLIGOMERIC ETHYLENE TERPHTHALATE. A GLYCOLIC SOLUTION OF TRETHYLAMMONUIM OR TRIPROPYLAMMONIUM GERMANATE IS EMPLOYED AS THE CATALYST IN THE PROCESS. THE CATALYST IS PREPARED BY ADDING THE RESPECTIVE TRIALKYLAMINE TO AN AQUEOUS-GLYCOLIC SLURRY OF GERMANIUM DIOXIDE. |
