Abstract

Prezenta inventie se refera la un procedeu continuu de obtinere a polietilentereftalutului, utilizat, prin filare directa din topitura, la obtinerea fibrelor poliesterice, firelor textile poliesterice, firelor tehnice poliesterice si la o instalatie pentru realizarea acestuia. Procedeul permite marirea gradului de esterificare, reducerea continutului de dietilenglicol, obtinerea de polimer cu vâscozitate ridicata, valorificarea deseurilor si obtinerea polimerului vopsit în masa.
