Study on the Activity of the Butadiene Polymerization with Molybdenum Catalyst Systen
【摘要】 本文报道了MoCl5-x(OnCBH17)x-(i-Bu)2AlOPhCH3(x=0,1,3)和MoCl4-y(OnC8H17)y-(i-Bu)8AlOPhCH3(y=0,1,2)体系催化合成1,2—聚丁二烯活性的研究。结果表明,钼体系催化丁二烯聚合活性按下列顺序排列: MoCl4(OnC8H17),MoCl5>MoCl2(OnC8H17)3,MoCl3(OnC8H17)>MoCl4>MoCl2(OnC8H17)2。四价钼体系合成的1,2—聚丁二烯的分子量分布较五价钼体系合成的1,2—聚丁二烯的分子量分布窄。
【Abstract】 In this paper, the activity of the butadiene polymerzation with MoCl5-x(OnC8H17)x-(i-Bu)2AlOPhCH3(x=0, 1, 3) and MoCl4-y (OnC8H17)y- (i-Bu)2AlOPhCH3 (y=0, 1, 2) catalysts has been studied. It has been observed that the sequence of the activity of the Catalysts is as follows: MoCl4(OnC8H17), MoCl5>MoCl2(OnC8H17)3, MoCl3(OnC8H17)>MoCl4>MoCl2(OnC8H17)2. The molecular weight distribution of polybutadiene has also been observed.
