近年来,为了研制耐水、阻燃、防腐以及高粘接强度的特殊涂层,开始对端羟基液体聚丁二烯(简称丁羟)进行氯化改性等方面的研究。但用NMR法研究氯化丁羟的结构,并未见文献报道。本工作主要讨论丁羟与氯化丁羟的NMR谱峰的归属以及微观结构的测定,讨论氯化丁羟的氯化度和氯含量的测定及其计算方法,得到了与燃烧法相一致的结果。
In recent years, in order to develop water-resistant, flame-retardant, anti-corrosion and high bonding strength of the special coating, began to hydroxyl-terminated liquid polybutadiene (referred to as butylated hydroxy) for chlorination and other aspects of research. But using NMR method to study the structure of butylated hydroxychloride has not been reported in the literature. This work mainly discusses the assignment of the NMR peak of butadiene and chlorobutyl chloride and the determination of microstructure. The determination of chlorination and chlorine content of butylated hydroxychloride and its calculation method are discussed. The results are consistent with the combustion method .
