[EN] A method of producing a cellulose derivative film, the method comprising: forming a film with a solvent cast method from a dope including a cellulose derivative satisfying following conditions (a) and (b): (a) at least one among three hydroxyl groups included in a glucose unit of cellulose is substituted by a substituent of which a polarizability anisotropy ?a represented as following Expression (1) is 2.5-x10-24 cm³ or higher: Expression (1): ?a =ax- (ay+ az)/2, wherein ax, ay and az is as defined in the specification; and (b) when a substitution degree by a substituent of which ?a is 2.5x10-24 cm³ or higher is PA, and a substitution degree by a substituent of which ?a is lower than 2.5x10-24 cm3 is PB, the PA and PB satisfy following Expressions (3) and (4): Expression (3): 2PA + PB > 3.0; and Expression (4): PA > 0.2. [FR] L'invention concerne une méthode de production d'un film en dérivé de cellulose. Cette méthode consiste à: former un film à l'aide d'une méthode de coulage de solvant, à partir d'un dopant comprenant un dérivé de cellulose satisfaisant les conditions (a) et (b). Les conditions (a) et (b) sont décrites comme suit: (a) au moins un groupe parmi les trois groupes hydroxyle compris dans une unité de glucose de la cellulose est substitué par un substituant dont une anisotropie de polarisabilité ?areprésentée par l'expression (1) est supérieure ou égale 2,5-x10-24

oluenesulfonyl)1,2-ethylenediamines compounds, TsN(H)CH2CH2N(H)PhX, were synthesized by the uncatalyzed ring opening reaction of N-tosylaziridine with p-X-aniline derivatives in purewater at 50 °C. No solvolysis product was observed and the only side product was that of a subsequent ring opening reactions of N-tosylaziridine with the product anilines leading to substituted diethylenetriamines, XPhN(CH2CH2NTs)2
