Abstract: In the production of aqueous polymer dispersions by free radical emulsion polymerisation of monomers, a mini-emulsion (I) is added before or during polymerisation. (I) is an aqueous emulsion, stabilised with a surfactant, which contains emulsified monomer droplets with a particle size of 10-500 nm and a co-stabiliser, dissolved in the monomer, which is at least twice as soluble in the monomer as it is in water. Also claimed are polymer dispersions obtained in this way.

Abstract: This is a process in order to prepare a dilute polymer dispersion by the emulsion polymerisation of the compositions that able to polymerise as free radically (monomers); contains addition of a mini emulsion prepared from dilute, surfactant containing a compound (common regulator) dissolved into drop monomers having emulsified drops between 10 and 500nm before or during the polymerisation of the monomers and its solubility inside the monomers is at least twice the solubility inside the water.

Abstract: The invention relates to combinatory methods for producing an array of n aqueous polymer dispersions by emulsion polymerization and for producing an array of m formulations of polymer dispersions, in addition to the arrays themselves. The methods are carried out at n or m spatially separated locations for the n or m formulations. To carry out the emulsion polymerization, monomers, an initiator, a dispersant and optionally additional components are reacted with one another in water, which acts as the reaction medium. To produce the formulations, aqueous polymer dispersions are mixed with other aqueous polymer dispersions and/or additional components. In all methods, each one of the n or m formulations differs from the other formulation in at least one respective parameter, which can influence the characteristics of the polymer dispersions or formulations that are obtained. The advantage of the invention is that said method allows a large number of aqueous polymer dispersions and formulations to be produced and characterized. This accelerates the development of aqueous polymer dispersions and formulations with optimized characteristics.
