| 摘 要： | 氧阴离子聚合(Oxyanion－initiated Polymerization)是一类新型的聚合方法[‘,’‘．利用个乙烯基苦醇钾作为功能性引发剂,引发甲基丙烯酸－2－(NJ－二乙氨基)乙酯聚合,形成末端带可聚合官能团的大分子单体‘”“．氧阴离子引发剂通常难以引发甲基丙烯酸烷基酯单体聚合,但却能引发甲基丙烯酸氨基酯类单体发生聚合．由于氨基乙酯基7位上氮原子的供电子性,它能与钾离子形成螫合物,使氧阴离子的亲核性增加,从而更具有活性,引发单体聚合．氧阴离子聚合具有速度快、活性高、反应温度接近室温和产物的单分散性好等特点．尽管目前还不清楚这种反…

| Abstract: | A novel well-defined water-soluble macromonomer based on 2-(dimethylamino) ethyl methacry-late(DMAEMA) was synthesized by using functional initiators such as potassium alcoholate of trimethylol-propane allyl ether via oxyanion-initiated polymerization. GPC and 1H NMR studies confirmed that themacromonomers had narrow molecular weight distribution and each Poly(DMAEMA) chain contained apolymerizable allyl group. The macromonomers were highly surface active in aqueous media. They havepotential applications in preparation of surface-clean and functional latexes both as effective stabilizers andas co-monomers. |
