<p>MAR17 1981 A process for the production of modified polymers, preferably as solutions in organic solvents, by polymerisation of Ia) 70 to 99.9 parts by weight of acrylic and/or methacrylic esters, Ib) 0.1 to 20 parts by weight of .omega. -hydroxyalkyl esters of acrylic, methacrylic, maleic and/or fumaric esters, the said dicarboxylic acids being optionally esterified on the second carboxylic group with an alcohol of from 1 to 12 C-atoms and Ic) 0 to 10 parts by weight of other unsaturated monomers, the sum of (Ia), (Ib) and (Ic) amounting to 100 parts by weight, in the presence of II) 5 to 40 parts by weight of terminal blocked alkyl-hydrogen polysiloxanes. Organic solvents containing the obtained modified polymers and usual curing agents for alkyl-hydrogen polysiloxanes are useful for treating fibrous material to give water-tight and water-repellent effects.</p> |
