  1. 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

    同時採用有機硅單體延遲滴加及添加水解抑制劑等技術,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,提高了聚合物大分子鏈中有機硅鏈節的含量;利用紅外光譜與差示掃描量熱儀對產物分子結構進行了表徵,並通過對共聚產物力學和吸水率的測試,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良的力學及耐水性能;從分子設計角度出發,利用醇解反應合成出水解、縮合反應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構進行了證實;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,且其聚合產物具有較高的力學及耐水性能。
  2. 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

    以上實驗結果表明,在復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合,改進了二者的相容性,拓寬了其阻尼功能區的低溫和高溫溫域;而在sin中通過改善組四川大學博士學位論文分間相容性,調節交聯密度控制其微相結構和兩種組分相對反應速度的快慢,進而控制材料阻尼性能的設計是行之有效的。
  3. The microphase seperation of s - sbs was also studied by transmission electron microscope. the difference of microphase seperation of sbs and s - sbs was compared by the way of staining the c = c by oso4

    通過用050 ;對雙鍵染色,比較了sbs與s - sbs在磺化前後聚苯乙烯相和聚丁二烯相的微相分離結構的差異,說明磺化改變了sbs的微觀結構。
  4. The reason was that pma was linear polymer and that the incompatibility of pdms and pma leaded microphase separation. additional, xps analyzed the three kinds of elements in surface and interior of ipn, the results indicated that the content of the elements c, si and 0 were misdistribution and different in surface as well as in interior of ipn. the reason was the poor compatibility of pdms and pma, and found that amount of initiator and the reaction rate effected the distribution

    另外,本論文還通過xps電子能譜儀對工pn材料的表層和內層的化學元素c 、 51 、 o進行分析,發現表層與內層中的三種元素的含量並不相同,也沒有規律可循,說明在形成ipn結構過程中,由於兩相相容性不一致,它們的微運動趨向于兩相分離,同時發現引發劑用量和反應速度對元素分佈影響較大。
