Abstract
Inventia se refera la un procedeu pentru obtinerea unor rasini diluabile cu apa, conform caruia se supune aductarii un acid alfa beta-etilic nesaturat ales dintre acid maleic, anhidrida maleica, acid fumaric, acid itaconic cu polibutadiena avand masa moleculara de 500....5000 si indice de iod peste 100 mg iod /100 g, la temperatura de 150....240 degree degree C, urmata de semifabricarea cu un poliol ales dintre neopentilglicol, trimetilopropan bis-fenol A dietoxilat, bis-fenol A dipropoxilat la temperatura de 100...200 degree C, în prezenta unor solventi total sau partial miscibili cu apa alesi dintre alcool butilic tertiar si diacetonalcool, dupa care produsul rezultat se modifica cu rasina fenolica la temperatura de 70.....160 degree C, se dilueaza cu apa la temperatura de 90....160 degree C si se neutralizeaza.
