摘要(Abstract)：

以聚酰胺-胺(PAMAM)为核,利用月桂酰氯对其端羟基进行改性,合成了一系列线性-树枝状聚合物(PAMAM-n),其中PAMAM和月桂酰氯的摩尔比分别为1:1(PAMAM-1)、1:3(PAMAM-3)、1:5(PAMAM-5)、1:7(PAMAM-7)。通过FT-IR、1H-NMR、凝胶渗透色谱(GPC)和羟值测定等手段研究了PAMAM-n的结构,产物的酯化率分别为12.54%、28.78%、43.30%和79.64%。同时研究了PAMAM-n的表面性能和粒径,其表面张力基本上趋于21.38~27.96 m N/m,溶液粒径分布在120.6~457.8 nm之间,其中PAMAM-3具有最为优异的表面活性。随后将性能优异的合成产物PAMAM-3应用于皮革加脂工序中,使用FT-IR、AFM和TG等手段研究了PAMAM-3处理后的蓝湿革的结构、热力学性能。结果表明,通过PAMAM-3处理后的蓝湿革与胶原纤维之间有较强的物理化学作用,并且加脂后的皮革柔软性和增厚性有所提高。
