The method for preparing an insaturated polyester resin intended to the fabrication of resin concretes, particularly for the repair of hydraulic concretes, consists essentially in mixing polyacidswith at least one particular polyalcohol, proceeding to the esterification and adding to the monomer of the obtained resin a terpolymer of the versatic acid of vinyl acetate and an acrylate. The resin thus prepared has a high resistance to alkalines and to the hydrolysis as well as a linear expansion close to that of hydraulic concrete. |
