Ⅰ.端羟基液体聚丁二烯的氯化 合成了一系列氯含量不同(5％～68％)的氯化丁羟。利用红外光谱、核磁共振观察了它们的双键变化。上述结果及氯含量与反应时间的关系表明:丁羟在四氯化碳中氯化时,首先进行加成反应,待双键饱和后,进行取代反应。 Ⅰ. Chlorination of terminal hydroxyl liquid polybutadiene A series of butylated hydroxychlorides with different chlorine contents (5% -68%) were synthesized. Using infrared spectroscopy, nuclear magnetic resonance observation of their double bond changes. The above results and the relationship between chlorine content and reaction time show that when butylated hydroxychloride is carbon tetrachloride, the addition reaction is carried out first, and after the double bond is saturated, the substitution reaction is carried out.
