Beschreibung
Zusammenfassung:	Provided is a film comprising a polymer composition comprising a polymer produced from ethylene, one or more branched vinyl ester monomers, and optionally, vinyl acetate, with an ethylene content in an amount ranging from 40 to 99.9 wt%, and having a melt index (I2) from 0.1 to 100 g/10 min ASTM D1238 (190°C and load of 2.16 kg). Also provided are a method of producing a film, an article comprising a film, a solar cell encapsulant comprising a film, a laminate comprising a film and a method of manufacturing an article. L'invention concerne un film comprenant une composition polymère comprenant un polymère produit à partir d'éthylène, un ou plusieurs monomères d'ester vinylique ramifiés, et éventuellement, de l'acétate de vinyle, avec une teneur en éthylène en une quantité allant de 40 à 99,9 % en poids, et ayant un indice de fusion (I2) de 0,1 à 100 g/10 min ASTM D1238 (190 °C et charge de 2,16 kg). L'invention concerne également un procédé de production d'un film, un article comprenant un film, un encapsulant de cellules solaires comprenant un film, un stratifié comprenant un film et un procédé de fabrication d'un article.
