ELECTRICALLY CONDUCTIVE METAL-FILLED POLYMER COMPOUND FOR 3D-PRINTING (VERSIONS) Russian patent published in 2018 - IPC C08K3/08 B29C67/04 

FIELD: electricity.

SUBSTANCE: electrically conductive polymer composition contains syndiotactic 1,2-polybutadiene (1,2-SPB) in the amount of 60-50 wt % as a polymeric base and a solder of Sn-63 or lead is the rest as a conductive metal filler. The version of composition contains syndiotactic 1,2-SPB in the amount of 70-50 wt % by as polymeric base, and as a conductive metallic filler: copper or aluminium for the rest.

EFFECT: increase in electrical conductivity and melt flow index for polymer composites intended for 3D printing.
