FLUORINE-FREE FIBROUS TREATING COMPOSITIONS INCLUDING ISOCYANATE- DERIVED ETHYLENICALLY UNSATURATED MONOMER-CONTAINING OLIGOMERS, AND TREATING METHODS |
摘要 |
A fluorine-free composition includes one or more compounds derived from a reaction mixture that includes: (i) at least one isocyanate-reactive (i.e., functionalized) oligomer comprising 2 to 20 repeating units; (ii) at least one polyisocyanate; (iii) optionally at least one additional isocyanate-reactive compound; and (iv) optionally at least one isocyanate blocking agent; wherein the isocyanate-reactive oligomer is made by the radical-initiated reaction of a reaction mixture comprising at least one mercaptan and at least one (meth)acrylate monomer, wherein the at least one (meth)acrylate monomer comprises at least one isocyanate-derived group (e.g., a urethane group or a urea group) and at least one hydrocarbon group having at least 16 carbon atoms (and in some embodiments, up to 60 carbon atoms). Such compositions are useful for treating fibrous substrates to enhance their water-repellency. |
