    摘要： Disclosed are aqueous dispersions of cationic urethane-acrylic copolymers containing fluorinated acrylic monomers characterized in that the dispersions are obtained by radical polymerization in aqueous dispersion of fluorinated and non-fluorinated acrylic monomers (A) and of vinyl terminated polyurethane-acrylates containing cationic groups (B). The present invention relates to aqueous dispersions of urethane-acrylic copolymers containing fluorinated acrylic monomers and to their use as finishing agents in oleo and water repellent treatment in the textile, leather and paper field and to a procedure for the preparation of the aqueous dispersions of polymers.

    摘要： A glyoxal and boron free purified cationic polygalactomannan may be prepared by reacting a polygalactomannan flour, a nonionically derivatized polygalactomannan flour, or a mixture thereof, with a cationising reagent, adjusting the pH to be from about 4 to about 6; cross-linking the cationic with glyoxal, and filtering and water washing the cationic polygalactomannan to produce a glyoxalated purified cationic polygalactomannan containing not more than 70% by weight of water. In some cases it may be desirable to introduce a buffering agent to the glyoxalated purified cationic polygalactomannan to regulate the pH to from 8.0 to about 9.5, when measured at 1% (dry matter) in water. In other cases, it may be desirable to remove water to produce glyoxal free purified cationic polygalactomannan in powder form. Such compounds are particularly useful in personal care products.
