【摘要】 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。更多还原

【Abstract】 It is found by us for the first time that using chloride silicane as the third componentof rare earth based catalyst system leads not only to making catalyst, homogeneous butalso to obtaining very high activity of the catalyst and stereospecifity for butadienepolymer. Polymer obtained by mehtioned catalyst system shows narrow MWD and has goodphysical properties of its vulcanizates.更多还原
