摘要

Abstract "Process for the production of polymer composites, polymer composite and use of polymer composites" The present invention relates to a process for producing polymer composites suitable for absorbing and storing aqueous liquids and the polymer composites obtainable by this process. . The invention further relates to the use of such polymer composites. the process comprises free radical polymerization of a monomeric composition m) a) 50 to 100 wt%, based on the total amount of monomers a and b, of at least one a monomer with a double ethylene bond and at least one neutralizable acid group; (b) 0 to 50% by weight of one or more comonomers b and i are different from monomers a and have a double ethylene bond, and c) 0 to 10% by weight based on the total amount of monomers a and b from at least one crosslink to wherein the polymerization of the monomer composition is carried out in an aqueous suspension of a water insoluble particulate substance s comprising cellulose or lignocellulose, the weight ratio of the monomer composition m to substance s being in the range of 9: 1 to 1: 9 and wherein the monomers used for polymerization are present in the aqueous suspension in neutralized, i.e. anionic, form at least 10 mol%, often at least 20% mol mol, particularly at a measurement of at least 30 mol% and especially at an average of at least 35 mol%.
