Abstract : Monomers, B-stage polymers, C-stage polymers, cured polymers and electrically conducting polymers of acetylene-terminated aromatic monomers containing three benzene rings separated by ethylene groups are disclosed. These new polymers can withstand aggressive environments and are particularly adapted for use in high temperature composites in addition to the utilization of their electrical conducting properties. Preparation of these materials is accomplished by melt polymerization and heat treatment at high temperatures.
