| 摘 要： | 以八甲基环四硅氧烷(D4)为单体，γ-氨丙基三乙氧基硅烷(KH550)为氨基改性单体，十二烷基苯磺酸(DBSA)为酸催化荆及阴离子乳化剂，进行氨基改性有机硅阴离子乳液共聚，用红外光谱(IR)表征合成聚合物结构。研究发现，该乳液共聚转化速率符合典型的D4本体可逆平衡聚合特征，并探讨了分子量及聚合物链浓度随反应的变化规律。此外，还研究了非离子乳化剂、搅拌强度对乳液外观及稳定性的影响。

| Abstract: | Amino modified anionic emulsion copolymerization of cyclosiloxanes was favourably carried with Octamethylcyclotetrasiloxane (D\-4) as monomer, 3-Aminopropyltriethoxysilane (KH550) as amino modified monomer, dodecylbenzenesulfonate (DBSA) as catalyst and emulsifier. The structure of polymer synthesized were examined with infrared spectroscopy (IR). The changing characteristic of polymerization rate and molecular weight together with reaction was investigated carefully. And the influence of emulsifier and stir's speed on latex particle diameter were studied, too. |
