    Abstract: Preparation of an aqueous polymer dispersion comprises radically initiated polymerization of an ethylenically unsaturated monomer in the presence of dispersing additives, optionally a water soluble organic solvent in an aqueous medium, where at least a partial quantity of ethylenic unsaturated monomer and an aqueous soluble organic solvent exists with an average droplet diameter of = 1000 nm (mini-emulsion). Preparation of an aqueous polymer dispersion comprises radically initiated polymerization of an ethylenically unsaturated monomer in the presence of dispersing additives, optionally a water soluble organic solvent in an aqueous medium, where at least a partial quantity of ethylenically unsaturated monomer and an aqueous soluble organic solvent exists with an average droplet diameter of = 1000 nm (mini-emulsion), where the mini-emulsion is prepared by a raw emulsion with an average diameter of >= 2 mu m, containing at least partial quantity of water, dispersing additives, ethylenically unsaturated monomer, optionally a water soluble organic solvent, and passed through a micro-porous membrane with an average pore diameter of = 1000 nm.

    Abstract: A process for preparing an aqueous styrene-butadiene polymer dispersion by free-radical aqueous emulsion polymerization of a monomer mixture M containing from 40 to 80% by weight of styrene as monomer M1, from 20 to 60% by weight of butadiene as monomer M2, and from 0 to 40% by weight, based on 100% by weight of monomers, of ethylenically unsaturated comonomers M3 other than styrene and butadiene by a monomer feed technique in the presence of from 0.05 to 0.5% by weight, based on 100% by weight of monomers, of at least one hydrocarbon HC having 6 to 20 carbon atoms, which is selected from compounds which on abstraction of a hydrogen atom form a pentadienyl radical or a 1-phenylallyl radical and from alpha-methylstyrene dimer comprises including at least 30% of the hydrocarbon HC in the initial charge to the polymerization vessel and supplying the remainder of the hydrocarbon HC to the polymerization reaction in the course of that reaction.

    Abstract: The invention relates to a coating composition comprising: (a) 10% to 99.9% by weight of resin based on the total weight of the coating composition; and (b) 0.1 % to 20% by weight of a formaldehyde scavenger based on the total weight of the coating composition, wherein the formaldehyde scavenger has at least one active methylene hydrogen and is solid at room temperature. The invention relates to use of a coating composition for removing free formaldehyde from the environment, wherein the formaldehyde scavenger has at least one active methylene hydrogen and is solid at room temperature.
