摘　　要：以六亚甲基二异氰酸酯(HDI)、聚乙二醇(PEG-600)、三乙醇胺(TEOA)、丙烯酸羟乙酯(HEA)等为原料,合成以双键封端的超支化聚氨酯(HPU),再与全氟己基乙基丙烯酸酯(C6F)、甲基丙烯酸十八酯(SMA)、丙烯酸羟乙酯(HEA)、丙烯酸丁酯(BA)等,通过自由基聚合,合成超支化聚氨酯氟代聚丙烯酸酯(HPUFA)。通过红外光谱(FTIR)、场发射扫描电镜(SEM)、接触角测量仪等对产物结构、性能进行了测试。结果表明,当n(NCO)/n(OH)=1.4时,HPUFA用量1.5 g/100 g乙酸乙酯时应用效果较佳;经HPUFA处理的织物接触角达到137.5°,静态吸水时间达9.5 h,疏油等级6级。Hyperbranched polyurethane with carbon-carbon double bond terminal as performing polymer was prepared from HDI,PEG-600,TEOA,and HEA. Subsequently,HPUFA was synthesized from C6 F,SMA,HEA,BA and the performing polymer by radical polymerization. The structure and properties of the product were investigated by FTIR,SEM,and contact angle measurements. The results show that the application effect of HPUFA was good when nNCO/ nOHwas 1. 4 and the content of HPUFA was 1. 5 g /100 g of ethyl acetate. The contact angle of fabric treated with HPUFA reached 137. 5° and the time of static water absorption reached 9. 5 h and the oleophobic grade was 6.
