Abstract
Inventia se refera la un procedeu de obtinere a granulelor poliesterice lucioase, care, în scopul asigurarii unor proprietati îmbunatatite si a constantei acestora foloseste alimentarea continua a dimetiltereftalat si etilenglicol cu un debit constant într-un sistem de trei reactoare în cascada, la presiune atmosferica sub perna de azot, al o temperatura de 185-210 degree C cu o durata de stationare de 10,5-11,5h, cu trecerea continua a diglicoltereftalatului obtinut într-un sistem de trei reactoare în cascada, unde are loc reactia de policondensare progresiva sub vacumm între 250 tori si 1,0 tori la o temperatura variind între 235-290 degree C cu o durata de stationare a mesei de reactie de 8-9h si evacuarea continua a polimerului.
