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,f_n为2.16,f_w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。
The China made hydroxylterminated polybutadiene (HTPB) has been characterized usingVPO, IR, GPC and TLC techniques. The polymer was found to have M_n=3220,M_w/M_n=1.69,f_n=2.16 and f_w=2.27 with its number average functionlity being inereasedwith molecular weight. The reliability of TLC to determine the functionality distribution ofHTPB has been discussed.
