Abstract: front page image
(EN)A process for producing a cellulose ester film which comprises thermally melting a cellulose ester having a water content of 5.0 mass% or lower at a melting temperature (Tm) of 150-300°C and forming the melt into a film by the melt casting method to produce the cellulose ester film, characterized by adding to the cellulose ester a compound having both a phenol moiety and a hindered amine moiety in the molecule.
(FR)L'invention concerne un procédé de fabrication d'un film en ester de cellulose comprenant la fusion thermique d'un ester de cellulose ayant une teneur en eau de 5,0 % en poids ou moins, à une température de fusion (Tm) de 150-300 °C, et la mise en forme du mélange en un film par une méthode de moulage après fusion, afin d'obtenir un film d'ester de cellulose, caractérisé par l'ajout à l'ester de cellulose d'un composé dont la molécule a à la fois un motif phénol et un motif amine empêchée.
(JA) 水分含有量5.0質量%以下のセルロースエステルを150°C以上300°C以下の溶融温度(Tm)で加熱溶融し、溶融流延法によって得られるセルロースエステルフィルムの製造方法であって、前記セルロースエステルにフェノール部及びヒンダードアミン部の両方を一分子中に有する化合物を添加することを特徴とするセルロースエステルフィルムの製造方法。
