Polymeric films with surface energies as low as 10 mN/m were prepd. from a mixt. of a hydroxyl-end-capped solventless liq. oligoester (SLO), a blocked polyisocyanate, and a novel fluorinated blocked isocyanate (FnB-NCO; the ratio of the fluorinated tail and the caprolactam blocking group: 1:1), with less than 4 wt % of fluorine in the films. The curing temp. demonstrated a significant effect on the reaction rate and the film wettability: a higher curing temp. led to a less significant surface enrichment of fluorine, esp. at a low F content (
