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

Rheology is formulated with different parameters defi ning the physics of dual-phase and cross-dual-phase. The rubbery behavior of thermoplastics is explained quite differently to conventional theory.

Rheo-fluidification experiments which are applicable to industry (injection molding, extrusion, sheet forming, etc.) are described and analyzed, including molding under conditions of reduced viscosity (up to several hundred percent). The application of this theory to industry has already been proven by a number of successful derived inventions.

Jean Pierre Ibar is, since 2011, Professor at the University of the Basque Country, Polymat Institute, Spain. He previously held other academic positions in the US, France, and China. From the mid-1970s until 2006, he worked in the US in leadership roles at the start-up companies he founded, especially on the technical and research sides. Some of the concepts presented in this book were developed into commercial products at these companies.
