Supported rare earth catalysts were made from Nd(OiPr)3 and the chlorides of the elements of ⅡA groups which were used as supporters of the catalyst.In the study on the relationship between the composition of s...
Catalytic characteristics of magnesium chloride supported rare earth catalyst system of Nd(OR) 3-n Cl n(n=0,1,2) in polymerization of butadiene was investigated.The result indicated that the ionic electronegativity of...
Supported rare earth catalysts were made from Nd(O-i-Pr)3 and the halides, especially chlorides of the ⅠA and ⅡA groups, used as catalyst supporters, for studying the relationship between the composition of suppor...
Supported rare earth catalysts were made from Nd(O i Pr) 3 and the chlorides as well as bromides of the elements of ⅠA and ⅡA groups which were used as supporters of the catalyst. In the study on the relationship be...
