High performance polymers were synthesized by ring-opening polymerization of the corresponding macrocycles. Di-chloro compounds were used to synthesize the macrocycles and were shown to be nearly as efficient as the more expensive di-fluoro compounds used in the past. Macrocycles are more soluble and easier to process than linear monomers. With the enhanced cost effectiveness provided by di-chloro starting compounds, macrocycles provide a synthesis route which is practical for industrial applications such as reaction injection molding.
