This book reviews several domains of polymer science, especially new trends in polymerization synthesis, physical-chemical properties, and inorganic systems. Composites and nanocomposites are also covered in this book, emphasizing nanotechnologies and their impact on the enhancement of physical and mechanical properties of these new materials. Kinetics and simulation are discussed and also considered as promising techniques for achieving chemistry and predicting physical property goals. This book presents a selection of interdisciplinary papers on the state of knowledge of each topic under consideration through a combination of overviews and original unpublished research.
