以丙烯酸甲酯和二亚乙基三胺为原料,通过缩聚反应制备了一种水溶性端氨基超支化聚合物(HBP-NH2);并以2,3-环氧丙基三甲基氯化铵(EPTAC)为改性剂,在水溶液中继续与船HBP-NH2反应,制备了端氨基超支化聚合物季铵盐(HBP-HTC).分别采用红外光谱(FT-IR)、核磁共振(1H-NMR)和凝胶色谱(GPC)分析表征了产物的结构及分子量,同时研究了HBP-NH2和HBP-HTC的溶解性能、抗菌性能、紫外吸收性能及热性能等,为其在纺织加工中的应用提供依据.结果表明,HBP-NH2和HBP-HTC具有良好的抗菌性能和紫外吸收性能,同时在H2O,二甲基亚砜(DMSO),C2H5OH和CH3OH等极性溶剂中具有优异的溶解性能.
