This book familiarizes readers with the proven strategies -- as well as the pitfalls -- involved in successfully synthesizing the different types of composites together with their various demands concerning the processing conditions and other influencing factors. Following an overview of the synthesis methodologies, the text goes on to discuss the most relevant polymer materials, including polyamides, polyolefines, polyacrylates, polyethylenes, polyurethanes, polyesters and polyepoxides.
