| titleOfInvention | Method for preparing poly (trimethylene terephthalate) |
| abstract | We present a process for the production of poly (trimethylene terephthalate) (PTT), which simplifies the manufacturing process using one or two reactors. The process for producing poly (trimethylene terephthalate) according to the present invention is carried out by using one or two reactors or one kneader extruder to prepare 1,3-propanediol and terephthalic acid or 1,3-propanediol and dimethyl terephthalate. Low molecular weight poly (trimethylene terephthalate) is fed to the feed inlet of the reactor or kneader extruder so that the molar ratio of propylene to terephthalate group is 1.1 to 2.2, and by direct esterification or transesterification in the reactor or kneader extruder. ), The polymerization catalyst and the additives are fed to the auxiliary inlet of the reactor or the kneader extruder, and the high molecular weight poly (trimethylene terephthalate) is Generated and directly connected to a reactor or kneader extruder And pelletizing the same. |
