Abstract
The reaction of diamines or triamines with epoxidized oils leads to different reactions of intra/intermolecular cross-linking and the disruption of the ester linkage. However, by controlling the reaction conditions of temperature, stoichiometry and catalyst, production of oxirane rings without cross-linking and/or disruption of ester group can be achieved. In this work, the synthesis of cross-linking aminated-epoxidized linseed oil resins in two stages is presented. The first one started with epoxidized linseed oil (55.4%) which was subjected to a partial aminolysis using three different amines (ethylenediamine, p-xylylenediamine and triethylenetetramine) and a ZnCl 2 catalyst. Products were characterized by FT-IR, 1H-NMR and DSC. In the second stage, the thermal cross-linking reaction (thermal cure) for obtaining cross-linked polymers was studied by calorimetry using isothermal experiments. These results were extrapolated for producing sheet molding thermally cross-linked polymers.
