本工作首次发现,用氯代硅烷为第三组份的环烷酸稀土催化剂,不仅是一真正的均相体系,且对丁二烯聚合具有很高的定向性及活性,所得聚合物具有较窄的分子量分布,最终产品具有良好的性能。
It is the first time to find out that the rare earth naphthenate catalyst with chlorosilane as the third component is not only a true homogeneous system but also has high orientation and activity to butadiene polymerization. Narrow molecular weight distribution, the final product has good performance.
