Abstract
Novel mono- or difunctional phenylacetylene-substituted Schiff's base monomers useful in the preparation of electrically conducting polymers is disclosed. On heating, these monomers melt to a viscous liquid state, and on continued heating above about 300.degree. C. polymerize to form an electrically insulating thermoset polymer. On further post-cure heat treatment, the polymer becomes electroconductive showing a bulk conductivity of at least 10.sup.-2 S/cm.
