Abstract

Inventia se refera la un procedeu pentru obtinerea unor polimeri de condensare termoreactivi, pe baza de diglicidil polieteri polihidroxilici, utilizabili ca lianti termoreactivi pentru lacuri si produse de acoperire pigmentate, conform caruia în scopul asigurarii unor pelicule cu proprietati fizico+chimice+mecanice si chimice îmbunatatite precum si a unor stabilitati de depozitare crescute, se aduce în reactie diglicidil esterul bisfenolului A, cu greutate epoxidica echivalenta cuprinsa între 400 si 2800 g/val cu un oligomer fenolic sau aminic cu functionalitate integral hidroxilica sau partial blocata prin esterificare cu alcooli alifatici inferiori în raport gravimetric polieter: oligomer cuprins între 5 : 0,5 si 5 : 2 sau cu un oligomer acrilic în raport polieter: oligomer de 1:12 pana la 1:2, la temperatura sw 110.....150 degree C, în prezenta unui amestec de solventi care asigura o condensare azeotropa izoterma.
