Abstract: 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.

Abstract: Aqueous polymer dispersions are produced by multi-stage emulsion polymerisation in which polymerisation in stage 2 and any further stages is carried out in presence of residual initiator from stage 1 or by adding more initiator and the temperature in the reactor is at least 70degreesC from the start of stage 1 to the end of the last stage. A method for the production of aqueous polymer dispersions by at least 2-stage aqueous emulsion polymerisation of unsaturated monomers involving (1) polymerisation of a first monomer mixture (M1) by the monomer-feed method in presence of a radical initiator (I1) to give an aqueous dispersion of polymer (P1), (2) further polymerisation by (2a) addition of a different monomer mixture (M2) in undiluted form to the dispersion and (2b) polymerisation of M2, and optionally (3) repetition of steps (2a) and (2b) in further stages (i), using a total amount of monomers (M2) which is 0.1-20 wt.% of the monomers (M1) polymerised in stage 1 and not adding (M2) before the addition of (M1) is complete. In this method, (a) polymerisation in stage 2 (and any further stages) is carried out in presence of residual initiator (I1) or by adding more (I1) and (b) the temperature in the reactor is at least 70degreesC from the start of stage 1 to the end of step 2b in the last stage. Independent claims are also included for (1) aqueous polymer dispersions obtained by this method (2) polymer powder obtained by evaporating volatile components from these dispersions.
