SOOT AND SOOT-CONTAINING POLYMER Russian patent published in 2011 - IPC C09C1/48 C08K3/04 

FIELD: chemistry.

SUBSTANCE: invention can be used in polymer mixtures for making articles such as mixtures based on acrylonitrile-butadiene-styrene resin (ABS). Soot is characterised by iodine number ranging from approximately 150 to approximately 600 mg/g; DBF absorption ranging from approximately 40 to approximately 90 cm³/100 g, ratio of specific apparent surface on nitrogen/specific outer surface from approximately 1.25 to approximately 1.70; colour power defined as Terlon L*, 1.7 or less; permeability pressure of water vapour of 23.0 mJ/m² or less. The soot, which is take in amount of 1.5 wt % or less when mixing with ABS using a three-step technique, provides colour power of the mixture in the mixed material L* equal to 4.6 or less; Izod impact strength with an incision equal to 13600 J/m² or more; dispersion factor during extrusion by pressing equal to 4.0 or less.

EFFECT: soot ensures good dispersion in the polymer.
