Notes:
Polymers from tetrakis(hydroxymethyl)phosphonium chloride (THPC) or tris(hydroxymethyl)phosphine (THP) with ammonia show similar thermal degradation, but appear to be of different chemical structure. Solution reaction of THPC with urea or melamine or by solid-phase reaction with urea gives products ranging from water-soluble liquids to hard, brittle, insoluble polymers. Reaction of THPC with piperazine yields products of low thermal stability.
