GPC法测定纺织油剂聚醚的分子量分布

DETERMINATION OF MOLECULAR WEIGHT DISTRIBUTION OF TEXTILE FINISH OIL POLYETHER BY GPC QUANTITATIVE METHOD

采用岛津双凝胶色谱柱体系建立了一套适用于纺织油剂聚醚（Ｍ＝１００～１００００）分子量分布分段测定的ＧＰＣ新方法，用该法对国产１５个样品进行分析，结果表明，质量较好的样品，都较低，且服从泊松分布，反之则质量较差。以酸为起始剂的聚醚分子量分布较窄。油剂聚醚的质量与其结构（起始剂种类和聚合度等）有关。

A new GPC quantitative method for determination of molecular weight distribution of textile Finish Oilpolyether( M=100～10000)was established by using SHIMADZU dual column system, and a number ofderterminated results showed, the quality of samples whose was smaller and molecular weight distri-bution fitted Parson Distribution was better.The molecular weight distribution of polyether with starter ofacid was narrow,The quality of polyether oiling agent was related to its stracture,such as starter and poly-merization degree, etc.
