The intermediate IV was Isolated by recrystallizatlon in anhydrous toluene under nitrogen once and then reacted with 2-hydroxylethyl acrylate to form a product mixture. EPB1 en. The method of claim 18, wherein said treatment of said substrate is accomplished by immersion, flooding, spraying, padding, foaming, kiss rolling, metering, or painting. For these massive and immobile substrates, application of treating liquids is most conveniently done by brush, roller or spray and cure must be accomplished at ambient temperature. A fluorochemical composition according to claim 15, wherein L 3 corresponds to the following formula: n is an integer of 2 to 20; Z represents the residue of a free radical initiator; R 5 is hydrogen or a methyl group; X 6 is O or NH; and L 5 is an alkylene group having 2 to 4 carbon atoms. Suitable end-capping agents typically include a mercapto group and a functional group capable of reacting with an isocyanate. Typically, optical fibers comprise a light carrying core, for example an inorganic glass such as fused silica or a polymer such as polymethyl methacrylate, and a cladding material having a lower refractive index than the core. Their fibers were highly water repellent. Examples and Comparative Examples C9-C12 This series of examples and comparative examples was run to illustrate that Polymers 15 and 16, both copolymers of this invention, are useful as surfactants in lowering the surface tension of various liquid neat high surface energy organic materials two different epoxies, plasticizer, polyol and would thus be effective in promoting the wetting and spreading on low surface energy substrates of coatings formulations employing such organic materials. These polymers contain a mixture of R F -substituted amide and secondary amino groups.

  • The present invention relates to a novel class of degradable, amorphous fluorochemical acrylate monomers, oligomers, and/or polymers.

    Fluorochemical acrylate polymers of this invention contain within the polymer backbone (co)polymerized units having the formula depicted in Formula III. The treatment comprises a water-soluble fluorochemical polymer containing only waxes, acrylates (both polymers and monomers), silicones (solvent-based.
    Polymer P9, containing no pendent silyl groups, performed comparably to Polymers P1-P8, which do contain pendent silyl groups, indicating that the presence of pendent silyl groups in the polymer is not required to attain a durable treatment resistant to water penetration and to staining.
