Abstract

Un proceso continuo para la produccion de poli(trimetilentereftalato). De acuerdo con el proceso, se alimenta en un prepolimerizador una mezcla líquida dealimentacion que comprende bis-3-hidroxipropil tereftalato y/o poliésteres de bajo peso molecular de 1,3-propanodiol y ácido tereftálico, teniendo la mezclalíquida de alimentacion una relacion molar de grupos propileno a grupos tereftalato de 1,1 a 2,2. El bis-3-hidroxipropiltereftalato y los poliésteres de bajopeso molecular se polimerizan enforma continua para formar un prepolímero de poli(trimetilentereftalato) y una primera corriente de subproductos gaseosos. Elprepolímero de poli(trimetilentereftalato) con una viscosidad relativa de por lo menos aproximadamente 5 se retira en forma continua del prepolimerizador, y sealimenta en forma continua a un polimerizador final, donde es polimerizado en forma continua para formar un polímero de poli(trimetilentereftalato) de mayorpeso molecular, y una segunda corriente de subproductos gaseosos. Se obtiene poli(trimetilentereftalato) de mayor peso molecular, con una viscosidad relativade por lo menos aproximadamente 17, que se retira en forma continua del polimerizador final.
