Abstract: The use of finely-divided polymer powder (I) containing UV absorber(s) for stabilising polymers against the effects of UV radiation. Independent claims are also included for (1) stabiliser mixtures containing (I) and other component(s) selected from organic phosphites, phosphines and phosphonites, sterically-hindered phenols, sterically-hindered amines, chromans and salts of zinc, calcium, magnesium, cerium, iron and/or manganese (2) a method for stabilising polymers against the effects of UV, oxygen and heat by adding effective amounts of such mixtures (3) polymers (especially polyolefins) stabilised against UV and possibly also against oxygen and heat, containing (I) (4) objects made from such stabilised polymers.

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 addition al 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 characterize d. This accelerates the development of aqueous polymer dispersions and formulations with optimized characteristics.
