Abstract [English] A polymer composition contains a polypropylene-based polymer, a vinyl ester containing copolymer which includes ethylene, one or more branched vinyl ester monomers, and optionally, vinyl acetate. A method for producing a polymer composition includes mixing a polypropylene -based polymer and a vinyl ester containing copolymer at a temperature in a range from 20 Ā°C to 300 Ā°C to form the polymer composition. An article contains the polymer composition. [French] La prĆ©sente invention concerne une composition polymĆØre contenant un polymĆØre Ć  base de polypropylĆØne, un copolymĆØre contenant un ester vinylique qui inclut de l'Ć©thylĆØne, un ou plusieurs monomĆØres d'ester vinylique ramifiĆ©s, et Ć©ventuellement de l'acĆ©tate de vinyle. Un procĆ©dĆ© de production d'une composition polymĆØre inclut le mĆ©lange d'un polymĆØre Ć  base de polypropylĆØne et d'un copolymĆØre contenant un ester vinylique Ć  une tempĆ©rature dans une plage allant de 20 Ā°C Ć  300 Ā°C pour former la composition polymĆØre.
