We hope this book has shown the reader the many accomplishments of the polymer chemistry community using anionic polymerization. But the potential for further contributions using these techniques is even greater. For example, the contributors to this volume have demonstrated the unique advantages of anionic polymerization in controlling the architecture and microstructure of polydienes. In the near future post-polymerization reactions on these different structures/microstructures will create novel polymeric materials for many industrial applications. This important topic should be further explored in academia and industry.
