Abstract (en)
[origin: WO0073218A1] The invention relates to the utilization of copolymers as inhibitors of calcium oxalate coatings, containing the following polymerized components: a) 10 to 80 % by weight percent maleic acid and/or maleic acid anhydride; b) 20 to 90 % by weight acrylic acid and c) 0 to 20 % by weight of at least one additional monomer which can be copolymerized with monomers (a) and (b) and having an average molecular weight ranging between 25,000 and 250,000.
