| titleOfInvention | METHOD OF OBTAINING POLYBUTYLENEREPHTHALATE |
| abstract | The invention relates to a method for producing polybutylene terephthalate (PBT), in which a mixture of butanediol (BDO) and terephthalic acid (TPA) is esterified in the presence of a catalyst solution and the esterification product is subjected to polycondensation. In order to avoid the formation of a precipitate in PBT, the catalyst solution contains from 0.05 to 10 wt.% Alkyl titanate, from 85 to 99 wt.% BDO, from 50 to 50,000 ppm of dicarboxylic acid and not more than 0.5 wt.% water. |
