Separating material

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.

Granules of azo-type compounds

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.

Oxidation of alkylcyanohydrazines to azo-bis nitriles using Oxone-potassium bromide in aqueous medium

Azo-bis nitriles were prepared in good yields and high purity by oxidation of corresponding 1,2-bis-dialkylcyano hydrazines using oxone-potassium bromide in aqueous medium.

Hydrosilylation of unsaturated compounds

A method for hydrosilylating an olefinically unsaturated compound comprising contacting the unsaturated compound with a source of silicon in the presence of an azo-containing free-radical catalyst, the hydrosilylated product being a useful crosslinking agent.
