Abstract
Procedeu de obtinere a unor rasini alchidice slabe, modificate cu ulei de rapita, prin metoda acidolizei cu anhidrida maleica, caracterizat prin aceea ca 28,0...32,0 parti în greutate ulei de rapita si 3...5 parti în greutate anhidrida maleica se încalzesc la 240 degree C, unde se mentin pâna la un continut de anhidrida maleica de 1%, apoi se introduc 12,4...16,4 parti în greutate anhidrida ftalica si 14,4...18,2 parti în greutate propilenglicol si se policondenseaza la 210 degree C pâna la atingerea unui indice de aciditate de maximum 20 mg KOH/g si a unui timp de scurgere prin cupa fi 4 mm, de 60...80 s al solutiei 80% în toluen, dupa care produsul de reactie se dizolva în toluen, se tipizeaza si se filtreaza.
