Effects of Cross-Linking Agents on Synthesis of Heat-Resistant Resin from Ethylene Tar

Ethylene tar (ET) was utilized as raw material, 1,4-benzenedimethanol and trioxane as crosslinking agent to prepare condensed poly-nuclear aromatic resin (COPNAR). FT-IR, 1H-NMR, TGA, elemental analysis, and improved Brown-Ladner calculation were systematically conducted for ET, COPNAR, and COPNAR/g...

More Information
Summary:Ethylene tar (ET) was utilized as raw material, 1,4-benzenedimethanol and trioxane as crosslinking agent to prepare condensed poly-nuclear aromatic resin (COPNAR). FT-IR, 1H-NMR, TGA, elemental analysis, and improved Brown-Ladner calculation were systematically conducted for ET, COPNAR, and COPNAR/graphite composites prepared via graphite molding. The ET average molecular structure parameters were calculated using improved Brown-Ladner method, the crosslinking agent was found an important factor for the COPNAR synthesis, and the obtained COPNAR and CONPAR/graphite composites exhibited highly beneficial heat resistance.
