Molding compositions having high rates of crystallization and suitable for being molded at a temperature of the mold not higher than 100.degree. C. to produce molded articles having an optimal combination of mechanical, physical, thermal properties and of surface appearance, comprising: a linear saturated polyester (A); a salt of a mono- or poly-carboxylic acid (B); an ionomer copolymer containing side carboxylic groups at least partially salified (C), and a solid inert inorganic substance (D) having a particle size not higher than 5 micrometers. Said compositions may be reinforced by reinforcing materials, preferably by glass fibers.
