摘　　要：用裂解色谱法(PGC)研究了不同环化度的环化顺1,4聚丁二烯(CPBd)。建立了测定CPBd环化度的方法。分析了不同实验条件下生成的CPBd的环化度,结果与NMR测定值一致。The cyclized cis-1,4 polybutadiene (CPBd) with different degree of cyclization has been investigated by pyrolysis-gas chromatography (PGC). The method for determining the degree of cyclization of CPBd was established. The degree of cyclization of CPBd formed under different experimental conditions was determined by PGC, and the results were consistent with those determined by NMR.

关 键 词：裂解色谱法 环化度 CPBd PGC
