<p><b>SIGRID LÜFTL, PhD,</b>is currently involved in researching the influence of artificial aging on the properties of polymer materials. She has worked as a research associate at the Institute of Materials Science and Technology at the Vienna University of Technology.</p> <p><b>VISAKH P.M.</b> is a Senior Researcher at the School of Chemical Sciences, Mahatma Gandhi University, India. He has been invited as a visiting student/researcher to about 15 European universities and is the editor of seven books.</p> <p><b>SARATH CHANDRAN</b> is working as a research fellow at the School of Chemical Sciences, Mahatma Gandhi University, India, and as a research fellow at the Centre for Advanced Materials and Industrial Catalysis, RMIT, Australia.</p>

<p><b>An excellent, unique, and up-to-date reference book on polyoxymethylene, its compounds, and nanocomposites, specifically dealing with synthesis, characterization, processing, morphology, and applications</b></p> <p><i>Polyoxymethylene Handbook: Structure, Properties, Applications, and Their Nanocomposites</i> summarizes many of the state-of-the-art technological and research accomplishments in the area of polyoxymethylene (POM). It discusses in length the polymerization and manufacture of polyoxymethylene and various types of additives, as well as the structure and crystallization behavior of POM and its thermal, physical, mechanical, flame retardant, chemical, electrical, and optical properties. The environmental impact of POM is also addressed.</p> <p>The 15 chapters in the handbook are written by prominent researchers from industry, academia, and government/private research laboratories across the globe. Because so few books have ever been published on polyoxymethylene, the handbook is a very valuable reference tool that truly serves as a “one stop” resource for readers and users seeking solutions to both fundamental and applied problems.</p> <p><b>Readership</b></p> <p>The handbook will be of interest to polymer science engineers and technologists, scientists, senior graduate students, researchers from R&D laboratories, and manufacturers who work with this polymer, both in industry and academia. These industries include the automotive, electronics, medical, and consumer goods sectors.</p>
