Provided is an emulsion polymerization method for carrying out emulsion polymerization of monomers using a reactive emulsifier in an aqueous medium in the presence of a polymerization initiator, the emulsion polymerization method being capable of solving problems such as an enhancement of a rate of copolymerization of the reactive emulsifier with the monomer, dissolution of a bubbling trouble, a more improvement of water resistance of a coating film, etc. The emulsion polymerization is carried out using one or two or more kinds of polymerizable unsaturated monomers X having at least one carbon-carbon double bond in a molecule, one or two or more kinds of reactive emulsifiers Y having at least one polymerizable group in a molecule, and one or two or more kinds of polyfunctional monomers Z1 having two or more polymerizable unsaturated groups in a molecule and having a molecular weight per functional group of less than 150, or one or two or more kinds of hydrophilic monomers Z2 having one polymerizable unsaturated group and a hydrophilic group in a molecule and having an average molecular weight of less than 250, with a proportion of the total use amount of the polyfunctional monomer Z1 or hydrophilic monomer Z2 to the total use amount of the reactive emulsifier Y being in the range of Z1 / Y = 1 / 3 to 1 / 30 or Z2 / Y = 1 / 1 to 1 / 30 in terms of a mass ratio.

A device for managing air flow within a volume and / or within the device throw area or range, which includes an air transfer component, an entrance to the device, air induction ports, directional vanes, and three exit zones that incorporate lattices. The device minimizes or eliminates air pockets, air stratification, inconsistent temperature, and increases interior air turns within the volume of air to be managed.
