用紫外／示差（ＵＶ／ＲＩ）双检测器ＧＰＣ成功地测定了端羟基聚了二烯的官能度、官能度分布及分子量分布。采用３，５－二硝基苯甲酸氯衍生后的端羟聚了二烯，测得的数均官能度和数均分子量与ＶＰＯ法所得结果基本一致。实验结果表明，端羟聚了二烯的官能度随分子量增加而增大。 The functionality, functionality, and molecular weight distribution of hydroxyl terminated polydienes were successfully determined by UV / RI double detector GPC. The 3,5-dinitrobenzoic acid chloride derivatized terminal hydroxyl polyadienes, the measured number average functionality and number average molecular weight and VPO method results are basically the same. The experimental results show that the terminal hydroxyl poly diene functionality increases with increasing molecular weight.
