摘要
简要介绍了目前合成端羟基聚丁二烯(HTPB)的自由基聚合法和阴离子聚合法,并简述这2种合成方法的优缺点。重点叙述了HTPB主链改性研究进展,通过对HTPB主链中的双键进行改性或利用嵌段共聚技术,可向HTPB主链上引入新的特征基团或某些功能性链段,从而赋予改性后的HTPB不同的性能,拓宽其应用领域。
The free radical polymerization method and the anionic polymerization method for synthesizing hydroxyl-terminated polybutadiene(HTPB)at present are introduced briefly,and the advantages and disadvantages of the two synthesis methods are simply described.The research progress in the main chain modification of HTPB is emphatically described.By modifying the double bonds in the main chain of HTPB or using the block copolymerization technique,the new characteristic groups or some functional segments can be introduced into the main chain of HTPB,so as to give the modified HTPB different properties,and broaden its application fields.
