METHOD OF PRODUCING ELECTROCATALYTIC COMPOSITION BASED ON POLYPYRROLE Russian patent published in 2009 - IPC C08G73/06 C08G61/12 C08F2/46 C08F4/80 C08F2/08 C08F2/24 C08F4/34 

FIELD: chemistry.

SUBSTANCE: method is described for producing electrocatalytic composition based on polypyrrole, involving polymerisation of pyrrole in the presence of platinised soot and surface-active additive, wherein the process is carried out under the effect of a radical initiator in an organic solvent at temperature of approximately 0°C, where the radical initiator is dicyclohexylperoxy dicarbonate, the surface-active additive is a product from reacting tertiary amine (CH₃)₂NR (R - aliphatic residue C_12-14) and propylene oxide in ethyl cellosolve, containing an ionic component - quaternary ammonium base (CH₃)₂RN⁺R¹(OH)^-, where R¹- propylene oxide oligomers and a nonionic component - propylene oligomers, and the organic solvent is ethyl cellosolve. After mixing, the components the mixture undergo vacuum treatment at 10^-2 mm Hg, and during the initiation process, the system is exposed to an acoustic field with frequency 20 to 22 kHz. Polymerisation process of pyrrole is carried out until obtaining an electrocatalytic composition system which is soluble in organic solvents. In this process electrocatalytic composition is obtained, with the following ratio of said components, wt %: pyrrole 15 to 17; platinised soot 6 to 8; surface-active additive 8-10; dicyclohexylperoxy dicarbonate 5-7; ethyl cellosolve - the rest.

EFFECT: design of an efficient method of producing electrocatalytic composition based on polypyrrole.
