ABSTRACT:
The object of the present invention are new thermoset resins having quickened curing, a process for their preparation, and their applications. The resins according to the invention consist, at least in part, of the products resulting from the polycondensation of one or more pyridine derivatives containing at least two methyl groups in the 2, 4 or 6 positions, with one or more aromatic dialdehydes, and the addition of one or more additives consisting of phenol compounds. These resins are used to the fabrication of composite materials.
