ABSTRACT:
A novel compound which polymerizes to a thermoset polymer and which pyrols to amorphous carbon, is selected from the group consisting of: ##STR1## where R.sup.1 is --C.tbd.C.phi.. A novel thermoset polymer is made by heating an aromatic acetylenic monomeric precursor with the formula: ##STR2## where R.sup.1 is --C.tbd.C.phi., and where R.sup.2, R.sup.3, and R.sup.4 are independently selected from the group consisting of --H and --C.tbd.C.phi., or a mixture of two or more of these compounds, to a polymerization temperature. A novel process for making amorphous carbon with high char yield and low porosity, comprises pyrolyzing an aromatic acetylenic monomeric precursor/polymer, or a mixture of two or more precursors/polymers to a temperature in excess of 450.degree. C.
