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.

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.
