Abstract
Inventia se refera la un procedeu pentru obtinerea rasinilor alchidice, conform caruia, izomerii acidului ftalic, anhidrida tetrahidroftalica, luati individual sau în amestec se aduc în reactie cu polioli la temperaturi de 150...250 degree C pîna la un indice de aciditate de maximum 25 mg KOH/g rasina, dupa care, în oligomerul rezultat se introduc 100% trigliceride de origine naturala si se încalzeste la aceeasi temperaturapîna la obtinerea unui produs omogen, în final introducîndu-se acizi cu 1...3 grupe hidroxilice si încîlzindu-se la aceasi temperatura pîna la obtinerea unui indice de aciditate de maximum 120 g KOH/g rasina 100%.
