Abstract
The invention concerns a process to manufacture a thermoplastic resin charged with mineral or carbonated matter, and possibly containing an organic impact modifier, through the introduction into the said resin of a comb polymer with at least one ethylenic unsaturation monomer, to which is grafted at least one polyalkylene oxide function. The resins then obtained which also form the subject of the invention have an improved impact resistance without their rigidity being degraded.
