    摘要: Provided according to embodiments of the invention are methods for the rapid production of a composition that includes a reactive blocked prepolymer. Such methods may include continuously mixing a first precursor composition and a second precursor composition, the first precursor composition including a polyisocyanate oligomer and the second precursor composition including an amine (meth)acrylate to produce the composition that includes a reactive blocked prepolymer.

    摘要: Self-dispersible mixtures (G) of oligomeric isocyanates (C) reacted in part with polyethylene glycol monoalkyl ether (A), which optionally contains propyleneoxy units, and optionally with a chain extender (K) and exhaustively blocked with an isocyanate-blocking pyrazole (B) are useful as auxiliaries in the finishing of fibrous material with oleophobicizing and/or hydrophobicizing finishes (F) comprising fluorocarbon polymers.
