ABSTRACT:
Ethylenically unsaturated, fluorine-containing urethane derivatives (see Formula I) whose urethane group is substituted on its carboxyl radical by a fluorinated organic radical and on its nitrogen atom by an unfluorinated, ethylenically unsaturated organic radical. Their preparation can be carried out by reacting ethylenically unsaturated, unfluorinated isocyanates with fluorinated organic hydroxyl compounds in bulk in the absence of water or advantageously in inert organic solvents or in ethylenically unsaturated monomers capable of polymerization which behave inertly under the reaction conditions, it being possible to obtain the urethane derivatives directly in liquid or highly viscous or waxy or solid or crystalline form.
Urethane derivatives prepared according to the invention are usually readily to very readily soluble in standard nonaqueous, nonpolar inert organic solvents or in various monomers capable of copolymerization. They can be polymerized or copolymerized in a free-radical way and used to prepare polymers or copolymers.
