Abstract

Procedeu de preparare a politereftaloiloxalamidrazonei prin reactia oxalbisamidrazonei de clorura de tereftaloil într-un sistem bifazic de solventi constituiti din apa, solventi organici inerti nemiscibili cu apa, în preyenta de acceptori de acid sbagitare, racind continuu cu apa mediul de reactie pentru mentinerea temperaturii între 0 si 60 degree C caracterizat prin aceea ca, în scopul obtinerii unor compusii macromoleculari cu viscoInventia se refera zitati ridicate, se adauga în faza apoasa sarurineutre alese dintre sulfati sau cloruri ale metalelor, sodiu, potasiu sau de litiu în proportie cuprinsa între 6,6 si 60 mmol/l l apa, dupa care în faza apoasa se introduce cantitatea prestabilita de clorura de tereftalat dizolvata în hexan, tetraclo rura decarbon, benzina eter de petrol, toluen sau xilen, realizîndu-se astfel sistemului bifatic necesar reactiei.
