Abstract
Invnetia se refera la un procedeu de obtinere a poliacetatuli devinil cu masa moleculara mare prin polimerizarea acetatului de vinil la o concentratie de 5 ... 7 mol/l în solutie omogena, utilizând ca solvent amestecul metanol-apa în proportie de 2/8 ... 3/7 în volume si ca initiator un sistem redox: persulfat de amoniu-trietanol amina la temperaturi cuprinse în intervalul 25 ... 45 grade C.
