Abstract
The invention discloses a novel method of functionalizing polyketone polymers by reacting with primary aromatic amines to form substituted pyrroles. The advantages of this method include but are not limited to permissible addition of small molecules to produce a wide variety of products, grafting of the polymer side chains to synthesize branched or comb polymers, and coupling reactions for controlling molecular weights.
