Recent Advances in Anionic Polymerization : Proceedings of the International Symposium on Recent Advances in Anionic Polymerization, Held April 13–18, 1986 at the American Chemical Society Meeting in New York, New York, U.S.A.

Over the years the field of anionic polymerization has attracted numerous outstanding scientists, and today it still is being pursued by many researchers all over the world. The exciting discovery of termination-less polymerization processes and living polymers culminating in the development of narrow molecular weight polymers, star polymers, and tailor-made block and graft copolymers, contributed immensely to the rapid expansion of polymer science. Areas of active research in anionic polymerization presently include the structure of ion pairs and their role in regulating polymer structure, ring opening polymerization of heterocyclic monomers, synthesis of well-defined block and graft copolymers including the application of macromers in such systems, telechelic polymers with functional end groups, and other topics. New developments in the organic chemistry of carbanions such as dipolar carbanions impinge on the field of anionic polymerization. More sophisticated characterization techniques have been instrumental in obtaining better correlations between the structure of polymers and that of intermediates leading to their formation. This book contains the proceedings of the international symposium on "Recent Advances in Anionic Polymerization and Related Processes" which was held at the 1986 spring meeting of the American Chemical Society. It was the first Polymer Division-sponsored meeting exclusively devoted to anionic polymerization since the Houston ACS meeting in the spring of 1980. The proceedings of that meeting were published in the book "Anionic Polymerization", ACS Symposium Series No. 166, edited by Dr. J. E. McGrath.
