Abstract

Se da a conocer un proceso continuo para la produccion de poli(trimetilentereftalato). De acuerdo con el proceso, se alimenta a un vaporizador una mezcla de alimentacion líquida que comprende bis-3-hidroxipropil tereftalato y/o poliésteres de bajo peso molecular de 1,3-propanediol y ácido tereftálico, teniendo la mezcla de alimentacion líquida una relacion molar de grupos propileno a grupos tereftalato de 1, 1 a 2,2. Se vaporiza en forma continua una primera corriente de productos derivados gaseosos en forma continua y se lo elimina del vaporizador, y se retira en forma continua del vaporizador un producto de reaccion líquido del vaporizador que tiene una relacion molar de grupos propileno a grupos tereftalato de menos de aproximadamente 1,5. El producto líquido de reaccion del vaporizador se alimenta continuamente a un prepolimerizador donde se lo polimeriza en forma continua para formar un prepolímero poli(trimetilentereftalato) y una segunda corriente de productos derivados gaseosos. El prepolímero poli(trimetilentereftalato) que tiene una viscosidad relativa de por lo menos aproximadamente 5 se retira en forma continua del prepolimerizador y se lo alimenta a un polimerizador final, donde se lo polimeriza continuamente para formar un poli(trimetilentereftalato) de peso molecular mayor y una tercera corriente de productos derivados gaseosos. El poli(trimetilentereftalato) de mayor peso molecular que tiene una viscosidad relativa de por lo menos 17 se retira en forma continua del polimerizador final.
