摘要：
Presently is described a free-radically polymerizable composition comprising a mixture of reaction products of i) at least one polyisocyanate; ii) at least one isocyanate reactive perfluoropolyether compound; iii) at least one isocyanate reactive compound comprising greater than 6 repeat units of ethylene oxide; and iv) at least one isocyanate reactive non-fluorinated crosslinker comprising at least two free-radically polymerizable groups.
