Abstract
Inventia se refera la un procedeu pentru obtinerea în solutie a unor poliesteri liniari neinflamabili prin policondensarea bisfenolului A tetraclorurat cu dicloruri ale acidului fenoxifosforic, caracterizat prin aceea ca, în scopul reducerii duratei de reactie, policondensarea se efectueaza în solutie de solventi clorurati alesi dintre cloroform, clorura de metilen, tetraclorura de carbon, dicloretan si în prezenta unui acceptor de acid, la temperatura de 40...80 degree C, timp de 1...2,5 h, dupa care polifosfonatul se precipita într-un nesolvent.
