Summary

Two methods for the synthesis of bifunctional carboxy polymers are described. In a first example, poly (oxyethylene) was reacted with a bromoalkyl ester via the sodium salt to yield di (carboxyalkyl) poly (oxyethylene) after hydrolysis. As second method, an one-step procedure is reported in which polyglycols were converted to dicarboxy polymers by polymer-analogous reaction with anhydrides of dicarboxylic acids. Several examples of various chain extending molecules with latent carboxyl functionality for the synthesis of carboxy-telechelic polymers are summarized.
