新型端胺基聚酰胺-胺树枝状大分子合成研究

Study on synthesis of a new type of amino-terminated polyamidoamine (PAMAM) dendrimer

研究了以丙烯酸甲酯、己二胺、对苯二酚为原料,采用发散法合成新型端胺基聚酰胺-胺树枝状大分子时,反应条件——温度、反应时间、催化剂对合成产物的结构的影响。利用该树枝状大分子的活性点分布均匀的特点,通过设计和控制树枝状大分子模板剂来控制纳米粒子材料的形状。

Using methyl acrylate, hexanediamine and hydroquinone as raw materials, a new type of amino-terminated polyamidoamine （PAMAM） dendrimer was synthesized through divergent method. Influences of reaction conditions, such as temperature, reaction time and catalyst, on the structure of prepared product were studied. Based on the uniform distribution of active points of dendrimer, the shape of nanoparticle materials was controlled by designing and controlling the dendrimer templates.
