Polyaromatic pyrazines |
| abstract |
POLYAROMATIC PYRAZINES HAVING HIGH-TEMPERATURE STABILITY ARE PREPARED BY THE CONDENSATION OF BIS-X-HALO-AROMATIC KETONES WITH AMMONIA, SAID POLYMERS HAVING UTILITY IN THE FORM OF FILM AND FIBERS. THE SOLUBILITY OF POLYMERIC POLYAROMATIC POLYIMIDES IS INCREASED BY HEATING WITH PEROXIDES, PREFERABLY IN THE PRESENCE OF A STRONG ACID. |
