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
   同時采用有機硅單體延遲滴加及添加水解抑制劑等技術(shù)，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過程中的過渡水解及縮合反應(yīng)，提高了聚合物大分子鏈中有機硅鏈節(jié)的含量；利用紅外光譜與差示掃描量熱儀對產(chǎn)物分子結(jié)構(gòu)進(jìn)行了表征，并通過對共聚產(chǎn)物力學(xué)和吸水率的測試，證實了本研究所制備的有機硅改性丙烯酸酯共聚物具有比純丙烯酸酯聚合物更優(yōu)良的力學(xué)及耐水性能；從分子設(shè)計角度出發(fā)，利用醇解反應(yīng)合成出水解、縮合反應(yīng)速率較慢的兩種新型不飽和有機硅單體： ?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異丙氧基硅烷；利用核磁共振對新型硅烷單體結(jié)構(gòu)進(jìn)行了證實；研究表明利用新型硅烷單體可以制備出高硅烷含量的有機硅改性丙烯酸酯乳液，且其聚合產(chǎn)物具有較高的力學(xué)及耐水性能。
3. The experimental results further demonstrate that the combination of incompatibility polydimethylsiloxane and polyacrylate by co - vulcanization improves the both compatibility and broadens the low temperature and high temperature functional region . while in sin , to improve microphase structures and damping properties , the design to increase compatibility between two compositions and modulate crosslinking density as well as relative reaction rate of two compositions , is also effective
   以上實驗結(jié)果表明，在復(fù)合橡膠阻尼材料中將聚硅氧烷與聚丙烯酸酯通過共混硫化相結(jié)合，改進(jìn)了二者的相容性，拓寬了其阻尼功能區(qū)的低溫和高溫溫域；而在sin中通過改善組四川大學(xué)博士學(xué)位論文分間相容性，調(diào)節(jié)交聯(lián)密度控制其微相結(jié)構(gòu)和兩種組分相對反應(yīng)速度的快慢，進(jìn)而控制材料阻尼性能的設(shè)計是行之有效的。
