| titleOfInvention | PROCEDURE TO REDUCE THE AMOUNT OF RESIDUAL MONOMERS IN THE WATERPROOF DISPERSIONS OF POLYMERS. |
| abstract | Method for reducing residual amounts of monomers in aqueous dispersions of polymers by final treatment with an initiator system, characterized in that the final treatment is carried out in the aqueous dispersion of polymer by the addition of an initiator system, which essentially comprises a) from 0.001 to 5% by weight, based on the total amount of monomers, used to obtain the polymer dispersion, a1) of an oxidizing agent R1OOH, where R1 means hydrogen, an alkyl group with 1 to 8 atoms carbon or an aryl group with 6 to 12 carbon atoms, and / or a2) a compound that releases hydrogen peroxide in aqueous medium, and b) from 0.005 to 5% by weight, based on the total amount of the monomers, used to obtain the polymer dispersion, of a reducing agent, prepared from b1) an aldehyde R2CH = O, where R2 means an alkyl group with 1 to 12 carbon atoms no, that it contains functional groups and / or that it can be olefinically unsaturated, and b2) an inorganic dithionite and c) catalytic amounts of a polyvalent metal ion, which can be presented with various levels of valence. |
