摘要:
The present invention provides new polymer compositions which contain novel substituted pyrazines or pyrazine derivatives ("NPD") which are functional and have useful application as a monomer (co-monomer) for a variety of high performance polymers such as polyester, polyarylate, polycarbonate, polyetherketones, epoxides, polyimides, polyamides, and polyamides-imides. These NPD have the general formula: ##STR1## wherein R.sub.1, R.sub.2, R.sub.3, and R.sub.4 are defined herein.
