Abstract: The present invention relates to a process for modifying an aqueous polymer latex of polymer particles that bear carboxyl groups comprising the mixing of the aqueous polymer latex with at least one silane compound of formula (1) at a temperature of at least 60° C.: (RO)3-nR1nSiR2X (1) wherein R is C1-C10-alkyl, C3-C10-cycloalkyl, C6-C10-aryl, C1-C10-alkoxy-C1-C10-alkyl, C2-C10-alkenyl, C1-C4-alkyl-C6-C10-aryl or C6-C10-aryl-C1-C4-alkyl, R is C1-C10-alkyl, C3-C10-cycloalkyl, C6-C10-aryl, C2-C10- alkenyl, C1-C4-alkyl-C6-C10-aryl or C6-C10-aryl-C1-C4-alkyl, R2 is a covalent chemical bond or a C1-C20-alkylene, in which non-adjacent methylene units can be replaced by O-groups, n is 0, 1, 2 or 3, and X is a radical having 3 to 10 carbon atoms and bearing an oxirane group. The present invention also relates to modified aqueous polymer latexes obtainable by such process and to the use of these polymer latexes as binders or co-binders for industrial varnishes.

Abstract: The present invention relates to use of an aqueous polymer composition containing a water-soluble or water-dispersible polymer P made of polymerized ethylenically unsaturated monomers M comprising. 30 to 90 wt.-%, based on the total weight of monomers M, of at least one monomer M1 selected from C1-C12-alkyl esters of monoethylenically unsaturated carboxylic acids, C6-C10-cycloalkyl esters of monoethylenically unsaturated carboxylic acids and monovinylaromatic hydrocarbon monomers, 5 to 30 wt.-%, based on the total weight of monomers M, of at least one monomer M2 selected from monoethylenically unsaturated monomers containing at least one acid group, and 5 to 40 wt.-%, based on the total weight of monomers M, of at least one monomer M3 different from M2 which has a reactive functional group being capable of being crosslinked, wherein the total weight of monomers M1, M2 and M3 corresponds to at least 90% of the total weight of monomers M; wherein the monomers M are selected such that the theoretical glass transition temperature according to Fox (Tgt) of the polymer P is at most 80° C.; and wherein the polymer P is dissolved or dispersed in an aqueous phase such that the acid groups of the polymer P are totally or partially neutralized; as a staining composition for porous materials. The present invention also relates to an aqueous polymer composition containing said water-soluble or water-dispersible polymer P made of polymerized ethylenically unsaturated monomers M and a crosslinking agent.
