COMPOSITION BASED THEREON Russian patent published in 2001 - IPC

FIELD: new blacks used in rubbers, elastomers, plastomers and polymeric compositions which comprise said new blacks. SUBSTANCE: said blacks have I₂No iodine adsorption number of 65-95 mg/g, primary particle size of less or equal to 20 nm; or I₂No iodine adsorption number of 100-112 mg/g, particle size of less or equal to 20 nm, dibutyl phthalate adsorption value of less or equal to 102 cubic cm/100 g; or I₂No iodine asorption number of 50-70 mg/g, primary particle size of les or equal to 25 nm; or black has iodine adsorption number of 50-85 mg/g, particle size of less or equal to 25 nm; CDBP of less or equal to 96 cubic cm/100g. Polymeric composition comprises, polymer e. g. polyethylene and said blacks. Composition has 0.5-300 weight parts of black per 100 weight parts of polymer. EFFECT: improved viscosity of the composition and improved water absorption thereof. 67 cl, 5 dwg, 79 ex, 6 tbl
