ABSTRACT:
A modified polyester-polyurethane resin is formed by reacting at least one polyisocyanate at least one polyol polyester that is prepared from at least one diacid or ethylenically unsaturated anhydride and at least one polyhydric alcohol, at least one ethylenically unsaturated monomer, at least one promoter of the decomposition of the catalyst peroxide, at least one catalyst of the isocyanate-alcohol reaction, and at least one hydroxylated (alk)acrylate and is used for the impregnation of oriented reinforcements. The resin makes possible quick molding, at moderate temperature, of parts with high mechanical properties.
