Abstract
Inventia se refera la un procedeu pentru obtinerea unor adezivi poliuretanici pentru obtinerea unor adezivi poliuretanici, conform caruia, se efectueaza reactia dintre 4,4'-diizocianat de difenilmetan sau amestecuri ale acestora cu toluilendiizocianat cu concentratia în NCO peste 80% de preferinâî peste 90%, acid acrilic 95%, polietilenadipat cu cifra OH cuprinsa între 30 si 120, de preferinta între 40 si 70, rasina epoxidica cu cifra OH cuprisa între 150 si 250, de preferinta 180 si 220, la temperaturi cuprinse între 20 si 70 degree C, de preferinta 30...50 degree C, într-un solvent aprotic, astfel încât raportul dintre gruparile uretanice si vinilice sa fie cuprinse între 0,01 si 50, de preferinta între 2 si 4.
