【摘要】 本文用W-碘-3-氧杂全氟戊磺酰氟为原料,经过三步合成反应,制得带二羟基官能团的含氟化合物:2,2’-〔N,N’-二乙基-3,8-二氧杂全氟癸二磺酰胺基〕二乙醇,然后让其与2,4-甲苯二异氰酸酯〔TDI〕反应,得到含氟短链聚氨酯〔FSU〕。用1,1,1-三氯乙烷作溶剂,将FSU配成3％浓度的溶液,皮革、织物经此溶液处理后,具有良好的防水和防化学药品腐蚀的性能。更多还原

【Abstract】 This paper reports the synthesis of 2,2′- （N, N′-biethyl-3,8-bioxaperflu-oroalkane disulfonyl amide） diol (C₁₆H₂₀F₁₆O₈S₂N₂)through three steps rea-ctions, such compound reacts with the tolylene-2,4-diisocyanate （TDI） to get theproduct of short chain polyurethane which contained fluorine （namely FSU inthis paper）. FSU were diluted with 1,1,1-trichloroethane. Whilst the leather andtextile were coated with 3% FSU solution by spraying, it can give leather andtextile a good resistance to water and chemicals.更多还原
