This first-of-its-kind publication reviews the most impor-tant literature on the synthesis, properties, and applications of telechelic polymers. Written by a group of internationally known ex-perts in the field, this text contains a review table which allows the reader to search for given polymers with given end groups. Over 1,250 references are listed, covering primary and review articles as well as patents. Chapters include the preparation of telechelics by stepwise polymerization, anionic polymerization, radical polymer-ization, cationic polymerization, ring-opening polymerization and controlled polymer degradation. Polyols for the polyurethane pro-duction are described, as well as halato-telechelic polymers. Also, a more theoretical contribution on the physical properties of net-works formed from telechelic polymers is provided.
