FIELD: chemistry. n SUBSTANCE: present invention relates to inorganic oxide extrudates used as catalysts or catalyst supports. Disclosed is an extrudate containing titanium dioxide and a comb-shaped polymer obtained through copolymerisation of an ethylene carboxyl-containing monomer with a polyether macromonomer, including acrylates or methacrylates of an oxyethylene and oxypropylene copolymer, wherein the extrudate contains a backbone polymer chain, a carboxyl-containing side chain and a side chain containing polyether, including an oxypropylene and oxyethylene copolymer, wherein the amount of titanium dioxide is not less than 10 wt %, and the amount of the comb-shaped polymer is not less than 1 wt % of the weight of the extrudate. Said extrudate which is annealed is also described. n EFFECT: improved mechanical properties of extrudates. n 7 cl, 4 tbl, 21 ex |
