Abstract

Inventia se refera la un procedeu de obtinere a unor adezivi pe baza de dispersii apoase de copolimeri acril-stirenici si consta în aceea ca se supune copolimerizarii un amestec cuaternar, format din 50...70% acrilat de butil, 5...10% metacrilat de metil, 20...40% stiren si 2...8% acid acrilic, în prezenta unei cantitati de emulgator ionic 1...3%, fata de amestecul de monomeri, constituit dintr-un copolimer anhidrida maleica acetat de vinil cu greutate moleculara cuprinsa între 5000 si 25000 si care contine 40...60% anhidrida maleica si 40...60% acetat de vinil, copolimerizarea avînd loc la temperatura de 70...95 degree C.
