This book describes the latest developments in paper conservation by using polymeric materials. A short introduction on polymer chemistry is given to highlight the polymer characteristics and properties. The book is then dedicated to the conservative problems and issues in the field of paper artworks. This practical book identifies the importance of each type of polymer, related to its nature and properties, from the point of view of paper conservation. With the help of schemes and tables, the polymers are classified in terms of characteristics and final uses in respect to this very complex material.
