ABSTRACT:
A method of converting a toxic composition containing an aldehyde to a composition which is substantially non-toxic. The aldehyde is reacted with a polymer having protic oxygen or nitrogen atoms, a polyimine or polyimine derivative, and an active aromatic to couple or react with the aldehyde-containing composition. Preferably, this aldehyde conversion process will yield a substantially fluid reaction product by way of a substantially irreversible reaction.
