More Information
Summary:A polymer composition [composition (M)], said composition (M) comprising i) at least one polyglycolic acid polymer [polymer (PGA)] and ii) at least one amorphous polyester [polymer (APES)], said polymer (APES) being present in the composition (M) in an amount of at least 0.10 and of at most 45 wt%, with respect to the combined weight of polymer (PGA) and polymer (APES). Method of making such composition and method of producing a multilayer stretched product from such composition. L'invention concerne une composition polymère [composition (M)], ladite composition (M) comprenant i) au moins un polymère de poly(acide glycolique) [polymère (PGA)] et ii) au moins un polyester amorphe [polymère (APES)], ledit polymère (APES) étant présent dans la composition (M) en une quantité d'au moins 0,10 et d'au plus 45 % en poids, par rapport au poids combiné de polymère (PGA) et de polymère (APES). L'invention concerne également un procédé de préparation d'une telle composition et un procédé de production d'un produit étiré multicouche à partir d'une telle composition.
