过氧化氢引发聚合的端羟基聚丁二烯活性羟基含量的测定

DETERMINATION OF ACTIVE HYDROXYL GROUP CONETENT OF HYDROXYL-TERMINATED POLYBUTADIENES FROM POLYMERIZATION INITIATED BY PERHYDROXIDE

应用化学反应动力学原理,测定过氧化氢引发聚合的端羟基聚丁二烯(HTPB)活性羟基的含量.测定结果与国外报导的核磁共振(NMR)测定同类产品的结果相近。该方法具有操作简便,再现精度好的优点.

The content of active hydroxyl in hydroxyl-terminated polybutadiene (HTPB) from polymerization initiated by perhydroxide, was determinated herein which principles of dynamics of chemical reaction was based on. The results got to be close to those reported abroad on the same kind of product measured by nuclear magnatic resonance (NMR). This method poccessed advantages of easy operation and good repeatability.
