摘要
采用溶液缩聚法,以碱为催化剂,由腰果酚、甲醛分别与乙二胺、二乙撑三胺、已二胺制备腰果酚醛胺聚合物,并通过元素分析(EA)、红外光谱分析(FT-IR)、凝胶渗透色谱(GPC)和热分析系统(DSC-TG)等对所制备的聚合物进行结构表征与性能测试.结果表明:该缩聚物分子结构中含有-OH,-NH-,-NH2等功能基;同时,腰果酚醛胺聚合物具有优良的固化成膜性、物理机械性能、耐化学介质性能和热稳定性,以及能与环氧树脂进行固化交联和吸附重金属离子的性能.
Cardanol aldehyde-amine polymers were prepared by solution poly-condensation of cardanol,formaldehyde and 1,2-ethanediamine,diethylenetriamine,1,6-hexanediamine using base as catalyst.The structures of the prepared polymers were characterized by EA,FT-IR,GPC and DSC-TG,and the performances of these polymers were also investigated.The results indicated that the condensation polymers had functional groups such as-OH,-NH-and-NH2 in their structures.Furthermore,the cardanol aldehyde-amine polymers had excellent film forming ability,physico-mechanical properties,resistance against chemical media and thermo-stability.The polymers could also cure with epoxy resin（ER）and adsorb heavy metal ions.
