Abstract
Procedeul de stabilizare a dimetiltereftalatului în stare de topitura , conform inventiei, se caracterizeaza prin aceea ca drept stabilizator foloseste un amestec ternar compus din 0,001-0,2% glicerina, 0,001-0,2% mono sau dietilenglicol, 5...10 ppm formit de potasiu sau acetat de sodiu la temparatura de 156 si 170 degree C.
