| titleOfInvention | PROCEDURE FOR REDUCING THE QUANTITY IN RESIDUAL MONOMERS IN WATERPROOF DISPERSIONS OF POLYMERS. |
| abstract | Process for reducing the amount of residual monomers in aqueous dispersions of polymers by subsequent treatment with an initiator system, characterized in that the subsequent treatment in the aqueous dispersion of polymers is carried out under the addition of an initiator system, which essentially comprises a) 0.001 to 5% by weight, based on the total amount of monomers used to obtain the dispersion of polymers, a1) an antioxidant agent R1OOH, where R1 means hydrogen, an alkyl group having 1 to 8 carbon atoms , or an aryl group with 6 to 12 carbon atoms, and / or a2) a compound that releases hydrogen peroxide in aqueous medium, and b) 0.005 to 5% by weight, based on the total amount of monomers used for obtaining the dispersion of polymers, b1) a compound -hydroxycarbonyl HO O R2 HC C R3, where R2 and R3, independently of each other, mean hydrogen and / or an alkyl group having 1 to 12 carbon atoms, which may contain functional groups and / or have olefinic unsaturation, R2 and R3, optionally by methylene groups, form a ring structure that may contain functional groups and / or have olefinic unsaturation, and / or b2) a compound that it releases such compounds - hydroxycarbonyl in aqueous medium, and c) advantageously catalytic amounts of a polyvalent metal ion, which can occur in various degrees of valence. |
