"This book is well organized and written for PhD students and professionals in polymer science and technology. Fundamental knowledge on polymer blends is presented with a well-organised introduction to the polymer blend systems and the method for the miscibility enhancement. The audience can gain necessary information on recent progress in the preparation, characterisation, and applications of polymer blends. The introduction on shape memory polymer blends, strain hardening in polymer blends, and directed assembly of polymer blends exhibits active research directions in the field of polymer blends."—Professor Mo Song, Loughborough University, Leicestershire, UK"… captures several elements missing in other published volumes on polymer blends. Examples are extensive coverage on hydrogen bonding, shape memory polymers, and cyclic linear polymer blends."—Sadhan C. Jana, Department of Polymer Engineering, University of Akron, Ohio, USA
