POLYMERIZATION CATALYST BASED ON MACROMOLECULAR PLATINUM COMPLEXES, THERMALLY CONDUCTIVE POLYMER COMPOSITION, METHOD FOR PRODUCING THERMALLY CONDUCTIVE POLYMER COMPOSITION AND ELASTIC THERMALLY CONDUCTIVE ELECTRICALLY INSULATING GASKET Russian patent published in 2017 - IPC C08F4/80 C08G77/08 C08L83/07 C08K5/54 

FIELD: chemistry.

SUBSTANCE: catalyst is proposed, based on platinum macromolecular complexes, in the structure of which, as ligands , the aminoterminal polydimethylsiloxanes of the general formula NH₂(CH₂)_k(OSi(CH₃)₂)_n-O-(CH₂)_kNH₂, where k=1-10, n=200-500. A thermally conductive polymer composition with the use of this catalyst, a method for its obtaining and the elastic conductive electrically insulating gasket produced from said cured composition are proposed as well.

EFFECT: improving the quality of the thermally conductive polymer composition and the final product obtained from this composition by moulding and subsequent heat treatment.
