端羟基聚丁二烯(HTPB)是一种重要的预聚物。据报道,HTPB的分子量(Mi)、分子量分布、官能度(f)和官能度分布对其物理和加工性能均有很大的影响。因此,对HTPB官能度分布的研究,具有十分重要的意义。 HTPB在聚合过程中,由于无法控制链的转移而产生了不同的官能度。预聚物的官能度被定义为预聚物的数均分子量(Mn)
Hydroxy-terminated polybutadiene (HTPB) is an important prepolymer. It has been reported that the molecular weight (Mi), molecular weight distribution, functionality (f) and functional distribution of HTPB have a great influence on their physical and processing properties. Therefore, the research on the distribution of HTPB functionalities is of great significance. HTPB in the polymerization process, due to the inability to control the chain transfer and produce different functionality. The functionality of the prepolymer is defined as the number average molecular weight (Mn) of the prepolymer,
