In this paper, a quaternary ammonium salt of chitosan was synthesized and the factors affect on the solubility or degree of substitution of product, such as the concentration of alkali, the time of basification, the content of water in system, the time of dispersing and the method of adding epoxyproryltrimethylammonium chloride, were discussed in detail. The product was characterized by IR, DSC, TG and X-RAY diffraction. The effects of time, humidity and temperature on the gases permeability of the quaternary ammonium salt of chitosan film were researched.

With the increasing of the concentration of alkali, the content of insolubility of the product reduces initially but increases later, the DS of product increases initially then reduces later. The product has good solubility and high DS at 10% content of alkali. The insoluble product reduces at initially and then keeps stability later with the time of basification extending. With the increasing of the content of water in system, theinsolubility of the product reduces initially and then increases later.
随着碱浓度的增加,产物中水不溶物含量先降低后增加,取代度先上升后下降,在10%时,水溶性最好,取代度最高;延长碱化时间,产物中水不溶物含量下降,之后趋于稳定;提高反应体系中水的含量,产物中水不溶物含量先降低后增加,在7%时,水溶性最好,延长分散时间,产物中水不溶物含量下降,取代度提高;醚化剂以少量多次的方式滴加,产物水溶性好。
