Abstract
Procedeu de obtinere a copolimerilor clorurii de vinil cu acetat de vinil avînd densitate în vrac ridicata, prin copolimerizarea monomerilor în suspensie apoasa, la temperatura de 60...65 degree C, la un raport al monomerilor de 60...95:40...5 parti în greutate, la raporturi monomere:apa de 1:1...3 în prezenta de stabilizatori de suspensie si initiator de polimerizare, întrerupator de catena, amestecul de reactie formîndu-se la temperatura de maximum 15 degree C si se mentine la aceasta temperatura timp de 30...180 min, de preferinta 30...60 min, dupa care temperatura se ridica la 60...65 degree C.
