The present invention provides a separating material producable by a) providing a solid substrate, having amino-functional groups coupled to the substrate surface, b) covalently coupling of the amino-functional groups with a thermally labile radical initiator, c) contacting the substrate surface with a solution of polymerizable monomers under conditions, where thermally initiated graft copolymerization of the monomers takes place, to form a structure of adjacent functional polymer chains on the surface of the substrate. The present invention further provides a method for the production of a separating material by a) providing a solid substrate, having amino-functional groups coupled to the substrate surface, b) covalently coupling of the amino-functional groups with a thermally labile radical initiator, c) contacting the substrate surface with a solution of polymerizable monomers under conditions, where thermally initiated graft copolymerization of the monomers takes place, to form a structure of adjacent functional polymer chains on the surface of the substrate.

-
, (2008/06/13)
A composition, comprising an azo compound in the form of granules having a diameter size of between 200 μm and 10 mm, the cumulative pore volume of said granules being between about 0.2 and about 2 ml per gram of composition. A process for preparing the composition is also provided, which comprises providing a wetted powder comprising the azo compound, effecting granulation by passing the wetted powder under mechanical stress, through a die, and then drying the granules so obtained at a temperature of at or less than about 45° C.
