Thermosettable compounds prepared from monohydroxy aromatic aldehydes and methylated pyridines or pyrazines.

摘要

Thermostable compounds are prepared by reac­ting methylated pyridines and/or pyrazines with one or more monohydroxy aromatic aldehydes having the ortho and para positions to the hydroxy group block with groups inert to condensation reactions. These com­pounds are useful to make unsaturated derivatives which can cure into high temperature resistant polymers and/or laminates without giving off condensation products.
