A novel aqueous two - phase system can be formed by the mixtures of a polymer and cationicanionic surfactants . such a system can be used as a partitioning system of proteins . in this work , we investigated the formation , phase behavior and protein partitioning in aqueous two - phase systems formed by dodecyltriethylammonium bromide / sodium dodecylsulfate / peg and dodecyltriethylammonium bromide / sodium dodecylsulfate / dextran . the ligands with affinity were attached to the polymers and the affinity partitioning of proteins was investigated . it was shown that the surfactants and polymers are enriched in different phases of aqueous two - phase systems . phase separation are promoted by increasing temperature and adding inorganic salts . different proteins are partitioned in different phases . the selectivity of protein partitioning is increased by adding ligands with affinity 报道了由正负离子表面活性剂与高聚物混合溶液形成的一种可用于蛋白质的分离及分析的新型双水相萃取体系.研究了正负离子表面活性剂(溴化十二烷基三乙铵/十二烷基硫酸钠)分别与葡聚糖和聚乙二醇混合双水相体系的形成规律、相行为及牛血清蛋白和溶菌酶在双水相体系中的分配.通过在高聚物分子中接上亲和配基，研究蛋白质在双水相体系中的亲和分配.结果表明，在该体系中，表面活性剂与高聚物分别富集于不同相中.升高温度及加入无机盐均可促进双水相体系的形成，不同蛋白质可分配于不同的相中.亲和配基的引入极大地增强了蛋白质分配的选择性
In this thesis , the development of emulsion polymerization theory and related new technologies are comprehensively reviewed , and the synthetic technologies of acrylate latex modified by organosilicon both at home and abroad are also reviewed . based on the current development and research in this field , attentions of this study are focused on three ways for preparing novel acrylate latexes modified by organosilicons , that is , 1 ) the acrylate monomers are copolymerized with unsaturated silicons by emulsion copolymerization ; 2 ) a new latex with microphase separation morphology is synthesized , which shows a core - shell structure character ; 3 ) soap - free polymerization is explored for preparing a higher - performance latex using an unsaturated silicon monomer , different acrylates and a reactive emulsifier . by using techniques of delaying addition of organosilicon monomer and a hydrolysis inhibitor , the hydrolysis and condensation of 3 - ( trimethoxysilyl ) propyl methacrylate during polymerization can be effectively prevented , as a result , organosilicon content in the macromolecular chain is increased 同时采用有机硅单体延迟滴加及添加水解抑制剂等技术，有效防止了-甲基丙烯酰氧基丙基三甲氧基硅烷在乳液聚合过程中的过渡水解及缩合反应，提高了聚合物大分子链中有机硅链节的含量；利用红外光谱与差示扫描量热仪对产物分子结构进行了表征，并通过对共聚产物力学和吸水率的测试，证实了本研究所制备的有机硅改性丙烯酸酯共聚物具有比纯丙烯酸酯聚合物更优良的力学及耐水性能；从分子设计角度出发，利用醇解反应合成出水解、缩合反应速率较慢的两种新型不饱和有机硅单体： ?甲基丙烯酰氧基丙基三乙氧基硅烷和?甲基丙烯酰氧基丙基三异丙氧基硅烷；利用核磁共振对新型硅烷单体结构进行了证实；研究表明利用新型硅烷单体可以制备出高硅烷含量的有机硅改性丙烯酸酯乳液，且其聚合产物具有较高的力学及耐水性能。
