Abstract
Procedeul de obtinere a terpolimerilor pe baza de etilena-propilena, conform inventiei, optimizeaza procedeul cunoscut, schimbând conditiile de reactie : temperatura creste pâna la 40 degree C, iar presiunea se mentine la 4 ... 5 at, în scopul obtinerii unui randament crescut, al unor consumuri de materii prime si energetice scazute. Aplicând procedeul conform inventiei, creste concentratia de terpolimer în reactor pâna la 6 % în greutate, scade cu circa 20 % consumul de soda de -17 degree C si cu circa 12 % consumul de propilena, în paralel îmbunatatindu-se si transferul de masa la reactorul de polimerizare. Astfel este posibila obtinerea unor sortimente cu continut ridicat de etilena.
