Abstract
Inventia se refera la un procedeu pentru obtinerea unor rasini alchidice cu continut scazut de ulei de ricin dehidroxilat, conform caruia, se efectueaza initial poliesterificarea uleiului de ricin cu trimetilolpropan sau propilenglicol cu anhidrida ftalica, la temperatura de 260-270 degree C pîna cînd vîscozitatea masei de reactie initial în scadere, începe sa creasca, dupa care se adauga o a doua portie de poliol si anhidrida ftalica continutul de ulei al rasinii initial de 50...70% scazînd la 20...34% si se continua poliesterificarea la temperatura de 200...240 degree C pîna la atingerea unui indice de aciditate de maximum 30 si un timp de curgere prin cupa viscozimetrica cu phi 4 la 20 degree C a solutiei de 50% în xilen, de 50...250 s.
