根据星型低顺式聚丁二烯（ＬＣＢＲ）的溶液性能和线型ＬＣＢＲ的ＭａｒｋＨｏｕｗｉｎｋ方程，推导出了星型ＬＣＢＲ的ＭａｒｋＨｏｕｗｉｎｋ参数Ｋ、α的值，并对不同臂数的星型ＬＣＢＲ进行了ＧＰＣ分析。结果表明，采用修改后的Ｋ、α值估算星型ＬＣＢＲ的ＧＰＣ谱图中的相对分子质量基本上是可行的。
According to the solution properties of star low cis-polybutadiene (LCBR) and Mark-Hauwink equation of linear LCBR, the Mark-Hauwink parameter K, α of star-shaped LCBR is deduced. Type LCBR GPC analysis. The results show that it is basically feasible to use the modified K, α values to estimate the relative molecular mass in the GPC chromatogram of star LCBR.
