| 摘要 |
Silicone-modified polymers of ethylenically unsaturated monomers are prepared in the form of aqueous polymer dispersions or water-redispersible polymer powders, by A) preparing a prepolymer by means of polymerization of one or more ethylenically unsaturated monomers and at least one ethylenically unsaturated silicone macromer and isolating the prepolymer, B) dissolving the prepolymer in one or more ethylenically unsaturated monomers, C) emulsifying this solution in water and polymerizing by a free-radical mechanism, and optionally D) drying the resulting aqueous dispersion of silicone-modified polymers.
