Zusammenfassung:	Composition comprising at least one vinyl halide polymer and 0.1 to 5% by weight, relative to the weight of the vinyl halide polymer, of at least one polymer of at least one acrylic ester obtained by polymerization in solution in a liquid medium comprising at least one chain transfer agent chosen among the C3 - C20 hydrocarbons containing at least one secondary alcohol function. Process for ifs manufacture, article obtained starting from this composition and use of this composition for manufacturing sheets and films via calendaring or for manufacturing profiles by extrusion. Process for the manufacture of a polymer of at least one acrylic ester which can be used in the composition. L'invention concerne une composition comprenant au moins un polymère d'halogénure de vinyle et 0,1 à 5 % en poids, par rapport au poids du polymère d'halogénure de vinyle, d'au moins un polymère d'au moins un ester acrylique, obtenu par polymérisation en solution dans un milieu liquide, comprenant au moins un agent de transfert de chaîne choisi parmi les hydrocarbures en C3-C20 contenant au moins une fonction alcool secondaire. L'invention concerne également un procédé pour sa fabrication, un article obtenu à partir de cette composition et l'utilisation de cette composition pour fabriquer des feuilles et films par laminage ou pour fabriquer des profilés par extrusion. Procédé pour la fabrication d'un polymère d'au moins un ester acrylique pouvant être utilisé dans la composition.
