PURPOSE: To obtain compositions containing crystallizable polymers in dispersion in non-aqueous diluents, further containing curable materials and not requiring an addition of stabilizers.

CONSTITUTION: Curable compositions containing a polymer phase in dispersion in a diluent of non-aqueous continuous phase, wherein the above polymer phase comprises crystallizable polymers selected from polyesters, polycarbonates and polyamides, curable solvents for the above crystallizable polymers which are miscible with the diluent of continuous phase and, optionally, auxiliary solvents, and also wherein the curable solvents are allowed to react at least partially with the crystallizable polymers, so as to form stabilizers for the dispersion.
