The invention relates to a process for producing polymer composites suitable for absorbing and storing aqueous liquids, to the polymer composites obtainable by this process, and to the use of the polymer composites. The process comprises free-radical polymerization of a monomer composition M comprising 50 to 100% by weight, based on the total amount of monomers A and B, of at least one monomer A having one ethylenic double bond and at least one neutralizable acid group, 0 to 50% by weight of optionally one or more comonomers B which are different than the monomers A and have one ethylenic double bond, and 1 to 10% by weight, based on the total amount of monomers A and B, of at least one crosslinker C.

The present invention relates to the use, for stabilizing polymers, in particular polyolefins, with respect to exposure to UV radiation, of fine-particle polymer powders comprising at least one UV absorber. The present invention further relates to stabilizer mixtures for stabilizing polymers with respect to exposure to UV radiation, oxygen and heat, which, inter alia, comprise these polymer powders, and to a process for stabilizing polymers, in particular polyolefins, with respect to exposure to UV radiation, oxygen and heat, which comprises adding, to the polymers, in particular to the polyolefins, an effective amount of these stabilizers. The present invention further relates to polymers, in particular polyolefins, which have been stabilized with respect to exposure to UV radiation or with respect to exposure to UV radiation, oxygen and heat, which comprise an effective amount of these polymer powders or, respectively, stabilizer mixtures, and to articles produced from these stabilized polymers, in particular polyolefins.

The present invention relates to the use of sterically hindered amines comprising one or more groups of the general formula (I) to stabilize inanimate organic material, more particularly plastics or coating materials, where Rand Reach independently, alike or different, are H, C-Calkyl, C-Ccycloalkyl, aryl, hetaryl or a heterocycle, R, R, R, and Reach independently, alike or different, are C-Calkyl, or Rand Ror Rand Rtogether are a tetramethylene or pentamethylene group, and Ris aryl or hetaryl. The invention further relates to methods of stabilizing inanimate organic material, especially plastics or coating materials. Additionally provided by the invention are selected sterically hindered amines comprising one or more groups of the general formula (I). Additionally provided by the invention are materials that comprise selected sterically hindered amines.
