    摘要： A continuous self-metered process of forming a multilayer film comprising at least two superimposed polymer layers comprising the steps of: providing a substrate; providing two or more coating knives which are offset, independently from each other, from said substrate to form a gap normal to the surface of the substrate; moving the substrate relative to the coating knives in a downstream direction, providing curable liquid precursors of the polymers to the upstream side of the coating knives thereby coating the two or more precursors through the respective gaps as superimposed layers onto the substrate; optionally providing one or more solid films and applying these essentially simultaneously with the formation of the adjacent lower polymer layer, and curing the precursor of the multilayer film thus obtained; wherein a lower layer of a curable liquid precursor is covered by an adjacent upper layer of a curable liquid precursor or a film, respectively, essentially without exposing said lower layer of a curable liquid precursor.

    摘要： Method of preparing urethane based fluorinated monomers comprising (i) reacting a fluorinated alcohol and an isocyanate functional non-fluorinated monomer or (ii) reacting in one or two steps a fluorinated alcohol, a polyisocyanate and an isocyanate reactive non-fluorinated monomer, wherein reactions (i) and (ii) are carried out in the presence of one or more reactive diluents, the reactive diluents having an ethylenically unsaturated group and being free of isocyanate reactive groups. The method does not require an inert organic solvent as a reaction medium, thus excluding volatile organic compounds (VOC's). The resulting compositions can be readily and conveniently used to prepare radiation curable coating compositions without the need to remove organic solvent from the composition.
