Abstract
Inventia se refera la un procedeu pentru obtinerea polietilenglicolilor, conform caruia, în scopul asigurarii unei omogenitati îmbunatatite, precum si al evitarii pericolului de explozii, carbonatul de etilena se supune încalzirii la temperatura de 135...190˛ degree C în prezenta de hidroxizi alcalini, în proportie de 5...10% în greutate, initierea lantului macromolecular si reglarea greutatii moleculare realizîndu-se cu apa sau etilenglicoli introdusi initial în masa de reactie.
