| 摘要 |
Soluble, curable triazine polymers are prepared by first polymerizing an aliphatic nitrile at a temperature of about 80 to about 450 DEG C in the presence of a catalyst such as a metal chloride to form a B-stage polymer, treating the B-stage polymer with a solvent such as diethyl ether to remove unreacted nitrile and finally extracting the soluble, curable triazine polymer from the thus-treated B-stage material with an alcohol, such as methanol. On heating, the soluble triazine polymers can be cured to form thermally-stable, insoluble, infusible polymeric materials.
