标准摘要
[中文适用范围]： 该测定方法适用于任何形式的增塑醋酸纤维素，例如模塑料、片材、制成品。 将增塑样品转化为薄膜，通过溶解和浇铸制备薄膜，随后在索氏提取器中用乙醚萃取。 通过在真空下加热并称重残余物来除去乙醚。 [外文原描述]： The determination method applies to plasticized cellulose acetate in any form, such as moulding material, sheet, manufactured articles. Conversion of the plastizised sample to a film, prepared by dissolving and casting, and subsequent extraction by ethylether in a Soxhlet apparatus. Removal of the ether by heating under vacuum and weighing the residual matter.
