摘要： 本文用VPO、IR、GPC、TLC方法表征国产端羟基聚丁二烯(HTPB),其结果是:Mn为3220,Mw/Mn为1.69,fn为2.16,fw为2.27。证明国产HTPB预聚物的数均官能度随分子量增加而增加。探讨了用TLC法研究HTPB官能度分布的可靠性。

Abstract: The China made hydroxylterminated polybutadiene (HTPB) has been characterized using VPO, IR, GPC and TLC techniques. The polymer was found to have Mn=3220,Mw/Mn=1.69,fn=2.16 and fw=2.27 with its number average functionlity being inereased with molecular weight. The reliability of TLC to determine the functionality distribution of HTPB has been discussed.

Key words: Hydroxylterminated polybutadiene, Functionality distribution, Characterization, Thin layer chromatography
