Abstract
Inventia se refera la un procedeu pentru obtinerea rasinilor epoxidice cu masa moleculara mare prin reactia de poliaditie dintre o rasina epoxidica cu masa moleculara mica, de ordinul 350...1500 si 2,2'-bis(4-hidroxifenil) propan în prezenta de 5...50 ppm LiCl calculat fata de amestecul de reactie, la temperatura de 150...200 degree C, conform caruia în scopul realizarii unei dispersii îmbunatatite a catalizatorului în masa de reactie, aceasta se introduce în amestecul de reactie sub forma unui concentrat de 1...20% din cantitatea totala de 2,2'-bis(4-hidroxifenil) propan.
