Abstract: Liquid polybutadiene(cis-1, 4 = 45-60%, trans-1,4 = 10-40%, vinyl = 15-40%, Mn=1500-6000) was prepared by using Co (naph)2-AliBu3-PhCCl3 as catalyst, extract gasoline as solvent and ethylene, propylene, isobutene as molecular weight regulator. The effect of α-olefine to butadiene molar ratio, polymerization temperature, monomer concentration, polymerization time on conversion, number-average molecular weight and microstructure of the productwere investigated. The adjusting mechanism of α-olef ine was proved.
摘要: 以环烷酸钴、三异丁基铝和三氯甲苯为催化剂,抽余油作溶剂,乙烯、丙烯和异丁烯为分子量调节剂,合成了顺式1,4含量为45—60%、反式1,4含量为10—40%、乙烯基含量为15—40%、数均分子量为1500—6000的液体聚丁二烯,考察了α-烯烃用量等因素对转化率、分子量及产物微观结构的影响.对α-烯烃的调节机理作了探讨.
