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 °C to 300 °C to form the polymer composition. An article contains the polymer composition.[French]
La présente invention concerne une composition polymère contenant un polymère à base de polypropylène, un copolymère contenant un ester vinylique qui inclut de l'éthylène, un ou plusieurs monomères d'ester vinylique ramifiés, et éventuellement de l'acétate de vinyle. Un procédé de production d'une composition polymère inclut le mélange d'un polymère à base de polypropylène et d'un copolymère contenant un ester vinylique à une température dans une plage allant de 20 °C à 300 °C pour former la composition polymère. Un article contient la composition polymère.
