It consists of two acetate radicals on each unit of D-anhydroglucopyranose of the cellulose molecule. It was first developed in the United States. It is distinguished from cellulose acetate and cellulose triacetate. It is fragile since it is based on cellulose. When cellulose diacetate deteriorates, it shrinks and releases acetic acid, causing a "vinegar syndrome". Cellulose diacetate was used to make fabrics, membranes, and filaments. From 1922 to 1957 it was used to make film stock, mainly in smaller formats such as 8 mm, 16 mm, 35 mm, and 70 mm. A cellulose diacetate film is also called a ''safety film''. The cellulose diacetate is biodegradable and hydrophilic. ==See also== * Cellulose acetate * Cellulose triacetate 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Cellulose diacetate」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
