Abstract

L'invention concerne des procédés de réduction du jaunissement et de l'odeur d'un article polyvinylique extrudé à chaud, comprenant les étapes suivantes : (a) préparation d'une composition d'alcool polyvinylique ; (b) extrusion à chaud de la composition d'alcool polyvinylique pour former un film ; et (c) traitement du film extrudé à chaud avec des niveaux élevés de lumière UV et de l'ozone, qui se sont révélés produire des effets de synergie, notamment en ce qui concerne le jaunissement et l'odeur.
