<p>The impact strength of moulded compositions of moulded polyamide resin is improved by incorporating into them an elastomer grafted with a polymer comprising repeated units of, as a percentage by weight, A) approximately 60 to approximately 95 of vinyl-aromatic monomer, B) approximately 5 to approximately 40 of at least one acid selected from the group comprising acrylic acid, methacrylic acid, partly neutralised acrylic acid, partly neutralised methacrylic acid, wholly neutralised acrylic acid and wholly neutralised methacrylic acid and C) 0 to approximately 15 of acrylate monomer.</p> |
