| 中文摘要: |
| 设计合成含胺类和烷氧基硅烷类官能基团的3种新型胺类封端剂，分别为N-苯亚甲基-3-三乙氧基硅烷基-1-丙胺（Imine TEOS）、N-对二甲氨基苯亚甲基-3-三乙氧基硅烷基-1-丙胺（Imine DTEOS）和N-苯亚甲基-3-三（甲氧基乙氧基乙氧基）硅烷基-1-丙胺（Imine GLYME），将其应用于阴离子聚合物的封端反应合成末端官能化聚苯乙烯（PS）和聚丁二烯（PB），并对其结构进行表征。结果表明：封端剂能与聚苯乙烯基锂进行等物质的量封端反应，成功实现封端反应制备官能化PS和PB，封端剂不会引发副反应。 |
| 英文摘要: |
| Three types of novel terminating agents with the amine and the alkoxysilane functional groups were synthesized:N-benzylidine 3-triethoxysilyl-1-propanamine (Imine TEOS),N-dimethylamino benzylidene 3-triethoxysilyl-1-propanamine (Imine DTEOS),and N-benzylidene-3-tris(methoxyethoxyethoxysilyl)-1-propanamine (Imine GLYME).The end functionalized polystyrene (PS) and polybutadiene (PB) were prepared with those terminating agents by living anionic polymerization technique,and their structure were characterized.The experimental results showed that,the well defined end functionalized PS and PB were successfully prepared by equal molar reaction of poly(styryl) lithium or poly(butadienyl) lithium with terminating agents without any side reactions. |
