The last twenty years have seen an extraordinary development and application of new modelling concepts and powerful simulation tools in the field of polymers, which have dramatically extended our understanding of structure-property relationships and impacted the design of these materials. This book provides a comprehensive overview of the theory and practice of polymer multiscale modelling methods with a balanced combination of breadth and depth. After introducing the key methods for modelling polymeric materials computationally at the atomistic and mesoscopic levels, the text discusses how bridges between different levels of modelling can be built with minimal loss of predictive ability. It presents the statistical mechanical foundations of these methods and explains how they should be implemented in order to understand and reliably predict structure and dynamics in systems of chain molecules. The book also covers the multitude of real world applications of these methods in polymer science ranging from chain conformation and packing, equilibrium volumetric behaviour, segmental dynamics and terminal relaxation in polymer melts to elastic constants, plasticity, and structural relaxation in polymer glasses, phase equilibria of polymer-solvent systems and miscibility of blends, microphase separation and morphology development in block copolymers and viscoelasticity of unentangled and entangled melts.

"A remarkable book which encapsulates the accumulated work of several generations of physicists, chemical engineers, and physical chemists. This is not merely a reference work but a lasting intellectual companion-one that both educates and inspires, and that will remain relevant for many years to come." - Alessio Zaccone, Università degli Studi di Milano

"This book is poised to become the new standard for implementing and practicing modern multiscale simulation. It is destined to be widely cited for years to come." - Professor Yuichi Masubuchi, Nagoya University

"In Multiscale Modelling of Polymers, Doros Theodorou and Vlasis Mavrantzas have produced a work that has the potential to become the definitive reference for computational polymer scientists and engineers seeking to bridge the gap between microscopic polymer physics and macroscopic behavior. ..This monograph stands as a significant and lasting contribution to the field, offering both a synthesis of established methods and a framework for future developments. It is more than a collection of literature; it is a pedagogical guide that organizes decades of scattered knowledge into a single, cohesive narrative." - Edward Maginn, University of Notre Dame
