Arrays of n aqueous polymer dispersions and m formulations of aqueous polymer dispersions

The present invention relates to combinatorial processes for preparing an array of n aqueous polymer dispersions by emulsion polymerization and for preparing an array of m formulations of polymer dispersions, and also to the arrays themselves. The processes are conducted at n or m spatially separate locations for the n or m mixtures, respectively. To conduct the emulsion polymerization, monomers, initiator, dispersants and, if desired, further components are reacted with one another in water as the reaction medium. To prepare the formulations, aqueous polymer dispersions are mixed with other aqueous polymer dispersions and/or further components. With all processes, each of the n or m mixtures differs from every other mixture in at least one parameter in each case which may have an influence on the properties of the resultant polymer dispersions or formulations, respectively. The advantage of the invention is that by means of these processes it is possible rapidly to prepare and characterize a large number of aqueous polymer dispersions and formulations. This leads to an acceleration in the development process for the preparation of aqueous polymer dispersions and formulations having optimized properties.
