| 摘 要： | 本文以正丁基锂作引发剂、甲苯作溶剂和链转移剂,通过分别添加二乙二醇二甲醚(2G)、四乙二醇二甲醚(4G)、六甲基磷三酰胺(HMPA)三种极性添加剂合成了分子量约2000—4000的1,2-液体聚丁二烯调聚物。实验中考察了三种极性添加剂对调聚反应的影响。根据实验结果及前人关于有机金属反应的机理,作者提出了新的求取链转移常数的模型,并运用该模型运算出三个体系的链转移常数。 |

| Abstract: | Liquid polybutadiene. telomers (M.W.2000-4000) are synthesized using n-BuLi as inititator, toluene as solvent and chain transfer agent with the addition of different polar modifiers 2G. 4G and HMPA. The effects of polar modifiers on the butadiene telomerization reaction are investigated in detail. Based on the results of synthesis a new model of chain transfer is proposed,and on this basis the chain transfer constants are calculated. |
