Process for preparing an aqueous polymer dispersion by polymerizing at least one ethylenically unsaturated monomer B in an aqueous medium in the presence of polymer particles A and at least one dispersant.

Method for the production of an aqueous polymer dispersion

A paper coating slip containing a mineral pigment and an aqueous polymer dispersion as a binder, wherein the polymer dispersion is obtainable by emulsion polymerization of ethylenically unsaturated compounds (monomers) and the paper coating slip gels at above 35&#xb0; C., i.e. the viscosity of the paper coating slip at from 35 to 60&#xb0; C. is at least twice the viscosity at 30&#xb0; C.

Paper coating slurries for cast coating

A process for the preparation of copolymer dispersions having a narrow particle size distribution, and exhibiting dilatant flow over a broad range of concentrations, by emulsion copolymerization of from 1 to 10% by weight, based on total monomers, of .alpha.,.beta.-monoolefinically unsaturated monocarboxylic acids and/or dicarboxylic acids with other monoolefinically unsaturated monomers and with from 0 to 5% by weight of polyolefinically unsaturated monomers in the presence of conventional emulsifiers, dispersants and polymerization initiators, and in the presence or absence of regulators, wherein the monomers are copolymerized in aqueous emulsion, with simultaneous agglomeration but only partial fusion of the initially formed polymer particles, at a temperature near the glass transition temperature of the copolymer formed, and thereafter

Binder for paper-coating compositions

Polyester fibers and cellulose fibers, and blends of these fibers, are dyed continuously with disperse dyes, or dispersed dyes, by continuous application of an aqueous dye liquor which contains, as the essential dyeing assistant, a polyoxyalkylated amine, a polyoxyalkylated amine-oxide and/or a quaternized polyoxyalkylated amine which in 1% strength aqueous solution has a cloud point of not less than 18.degree. C and which is derived from amines which contain at least 2 nitrogen atoms and at least one group which can be oxyalkylated, followed by drying and fixing.

Continuous dyeing of polyester fibers and cellulose fibers

Opacifying agents for liquid detergents, cleaning agents and cosmetic compositions, obtained by free-radical emulsion polymerization of styrene or emulsion copolymerization of styrene with methacrylates or acrylates in the presence of sodium polyacrylate having a K value of 15 to 35 and sarcosides of unsaturated fatty acids, the solid polymer particles having a softening point above 90.degree. C.

Opacifying agents

Nonwovens of natural and synthetic fibers which are bonded uniformly over the whole cross-section are obtained by using as binders aqueous polymer dispersions containing as heat-sensitizing agents alkoxylated amines having inverse solubility and a pH of less than 6.
