Abstract

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 its 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.
