摘要
用凝胶渗透色谱法(GPC)测定端羟基聚丁二烯(HTPB)官能度分布。将HTPB用3,5-二硝基苯甲酰氯在一定条件下进行衍生化反应,衍生化后的HTPB经GPC的示差/紫外(RI/UV)双检测器进行检测,所得的色谱图经数据处理,得到HTPB的官能度及其分布。
The functionality distribution of hydroxy-terminated polybutadiene（HTPB） was determined by gel permeation chromatography（GPC）. Derivative reaction of the HTPB was carried out by using 3,5-dinitrobenzoyl chloride under specific conditions. The derivation products of HTPB were determined by GPC with double detectors of refractive index/ultraviolet（RIAlV）. The functionality and its distribution of HTPB were obtained via data processing of the obtained chromatogram.
