摘要
介绍了气相色谱法测定硅酮改性聚氨酯中甲氧基含量的方法。硅酮改性聚氨酯中甲氧基与氢氧化钾正丁醇溶液加热回流反应,生成的甲醇用毛细管柱OV-225(ф0.32mm×30m×0.50μm)分离,用外标法测定从而计算出甲氧基的含量。
This paper introduced the method of mothoxyl group content in silicone modified polyurethane by gas chromatography.The methoxyl groups in silicone modified polyurethane react with potassium hydroxide solution in butanol under reflux heating condition,the generated methanol is separated with a capillary column OV-225（Ф0.32mm×30m×0.50μm）and measured by external standard method. So the content ofmethoxyl group is calculated.
