| Summary |
Understanding of polymer interactions is important for effective processing of plastics and their blends, mixing with nanoparticles, and understanding of their mechanical and physical properties. This book describes a new physics of interactions in polymers that challenges existing theories, and explains the concept of entanglement in a new way. |
