Abstract

La présente invention concerne une composition de moulage à base de copolyester. Cette composition contient au moins environ 30 % d'un copolyester d'un polyméthylène-glycol comportant 2 à 6 atomes de carbone, d'un acide gras dimère et d'un acide dicarboxylique aromatique ne comportant pas plus de 2 noyaux benzéniques dans lequel les deux groupes carboxyle n'occupent pas des positions péri ou ortho, la composition étant caractérisée en ce que le copolyester présente une viscosité intrinsèque comprise entre 0,5 et 1,5 dl/g et en ce qu'il comporte 1 à 30 % en poids d'acide gras dimère. Ces compositions servent à préparer des articles moulés par injection, de résistance élevée au choc et de bonne résistance à la déformation thermique.The present invention relates to a copolyester-based molding composition. This composition contains at least about 30% of a copolyester of a polymethylene glycol having 2 to 6 carbon atoms, of a dimer fatty acid and of an aromatic dicarboxylic acid having not more than 2 benzene rings in which the two carboxyl groups do not occupy peri or ortho positions, the composition being characterized in that the copolyester has an intrinsic viscosity of between 0.5 and 1.5 dl / g and in that it comprises 1 to 30% in weight of dimeric fatty acid. These compositions serve to prepare injection molded articles of high impact strength and good resistance to thermal deformation.
