摘　　要：采用发散法合成聚酰胺-胺(PAMAM)树形大分子,讨论了反应温度、反应时间和投料摩尔比等因素对反应的影响,并利用红外光谱、紫外光谱进行表征及酸碱滴定进行端基分析.根据仿生学原理,在室温、近中性pH和以正硅酸乙酯为原料等条件下,研究了PAMAM在体外介导聚合形成纳米SiO2的过程,结果表明有"人造蛋白"之称的树状化合物PAMAM介导效果显著.The polyamidoamine（PAMAM） had been synthesized by divergent synthesis using ethylenediamine as raw material by means of Mickeal addition reaction and amidation reaction with methylacrylate and ethylenediamine.The effects of reaction temperature,reaction time,the ratio of feed on the reaction were examined and the reaction characteristic was discussed.The nano-silicon polymerization was caused by PAMAM dendrimer based on bionics principle by using tetraethyl orthosilicate（TEOS） at room temperature and nearly pH 7.0.The results showed the interposition effect is prominent.
