The present invention relates to a process for preparing an aqueous dispersion of polymer particles by radical aqueous emulsion polymerization and also to the use thereof in paints, paper coatings, foams, crop protection compositions, cosmetic compositions, liquid inks, or thermoplastic molding compounds.

Method for producing aqueous dispersions

The present invention relates to aqueous binder compositions comprising an aqueous polymer latex of a film forming carboxylated polymer and a branched polyetheramine polyol dissolved in the aqueous phase of the aqueous polymer latex, wherein essentially all of the amino groups in the branched polyetheramine polyol are tertiary amine groups. The present invention also relates to water-borne coating compositions containing such an aqueous binder composition.

Aqueous binder compositions

Disclosed herein is a process for preparing an aqueous polymer latex by polymerising a monomer composition M by a radical emulsion polymerisation, where at least 95% of the monomer composition M is metered during a period P to the polymerisation reaction under polymerisation conditions, such that during at least one period P(n) within the period P, the relative amount of monomers M2, which are metered to the polymerisation reaction during the periods P(n), to the total amount of the monomer composition M, which is metered to the polymerisation reaction during said period P(n), is at least 1% by weight higher than the relative amount of monomers M2, which are metered to the polymerisation reaction outside of each of said periods P(n), to the total amount of the monomer composition M, which is metered to the polymerisation reaction outside of each of said periods P(n).

Process for preparing an aqueous polymer latex

The present invention relates to latex paints containing a) a multistage carboxylated polymer latex binder obtainable by multistage aqueous emulsion polymerisation of at least one non-ionic monomer which is selected from C-C-alkyl esters of acrylic acid, C-C-alkylesters of methacrylic acid, and vinyl aromatic monomers; one or more monoethylenically unsaturated monomers M2, which are selected from monoethylenically unsaturated monocarboxylic acids having 3 to 6 carbon atoms and monoethylenically unsaturated dicarboxylic acids having 4 to 6 carbon atoms, and where in at least one stage, monomers M2 added in this stage is at least 6% by weight; b) a titanium dioxide pigment; c) a polymeric dispersant selected from monoethylenically unsaturated monocarboxylic acids having 3 to 6 carbon atoms and monoethylenically unsaturated dicarboxylic acids having 4 to 6 carbon atoms, where the monomers make up at least 85% of the monomers forming the polymeric dispersant; and d) a thickener polymer.

Latex paint containing titanium dioxide pigment

The present invention relates to a method of producing emulsion polymer particles having a core-shell structure wherein at least one polyalkylene oxide containing additive is used in the core, and also to their use in paints, paper coatings, foams, crop protection agents, liquid inks and cosmetic compositions.

Method for producing emulsion polymerisates

The present invention relates to a process for producing emulsion polymer particles having a core-shell structure, wherein the weight ratio of the shells is within specific limits, and also to their use in paints, paper coatings, foams and cosmetic compositions.
