【摘要】 采用发散法合成了以乙二胺为核的半代聚酰胺-胺(PAMAM),研究了其在酸性条件下的水解反应,采用傅立叶变换红外光谱和核磁共振法对PAMAM水解酸进行了表征。测定了半代PAMAM水解酸的溶解性、熔点、热稳定性等性能,并对其性能变化的规律进行了探讨。通过丙烯酸羟乙酯与半代PAMAM水解酸的反应,合成了在紫外光作用下能固化成膜的树枝状PAMAM紫外光固化树脂。更多还原

【Abstract】 A series of polyamidiamine half generation PAMAM dendrimer were synthesized by means of divergent procedure.Half generation were hydrolysised in acidic conditions.Their compositions and structures were characterized by means of FTIR and 1H-NMR.The properties of the hydrolysalte were measured,such as solubility,melting point,heat stability etc.The variation rule of the different generation were researched.The hydrolysis products were modified with Hydroxyethyl acrylate,and the branched UV-cured PAMAM resin was synthesized.更多还原
