By n duality of fluorine alcohol, IPD I, polyester mellow, DMPA and TMP synthesized colophony of latex of fluorine modified polyurethane, small to its detached degree and exterior function undertook study. The result makes clear, after fluorine modified, the small detached rate of polyurethane of ability in swimming rises, fluorine carbon catenary comes easily in surface layer in 150-200 μ M rich collect. The osculatory part that water does film to go up in fluorine modified polyurethane has than common PU increase apparently, it is when mark of quality of the DFA in FPU 1% when, osculatory horn achieves 70 ° , water-resistance can increase.
