A utilização de materiais poliméricos em aplicações inovadoras, com técnicas cada vez mais aperfeiçoadas, deve-se ao progresso no conhecimento das correlações entre estrutura e propriedades. Em nenhum outro material de engenharia, as diferenças estruturais e variáveis de processo estão tão intimamente ligadas ao desempenho como nos polímeros. A intenção deste livro é abordar as correlações entre estrutura química, composição, características morfológicas de sistemas poliméricos e propriedades macroscópicas, proporcionando um balanço entre conhecimento teórico e aplicação prática dos conceitos fundamentais da ciência dos polímeros. Sem a pretensão de cobrir todo o panorama, a obra Fundamentos da ciência dos polímeros apresenta-se em nível intermediário, sendo útil tanto para os iniciantes quanto para os leitores mais experimentados.

This is a new, basic introduction to polymer science. It is both comprehensive and readable. The authors are leading educators in this field with extensive backgrounds in industrial and academic polymer research. The text starts with a description of the types of microstructures found in polymer materials. This provides an understanding of some of the key features of the various mechanisms of homopolymerization and copolymerization which are discussed in following chapters. Also discussed in these chapters are the kinetics and statistics of polymerization, with a separate chapter on the characterization of chain structure by spectroscopic methods. The next part of the text deals with chain conformation, structure and morphology, leading to a discussion of crystallization, melting and glass transition. The discussion then moves from solid state to solution properties where solution thermodynamics is introduced. This provides the basis for discussion of the measurement of molecular weight by various solution methods. The final chapter deals with mechanical and rheological properties which are discussed from a phenomenological continuum approach and then in terms of a fundamental molecular perspective. Altogether, this new text provides a comprehensive, readable introduction to and overview of polymer science. It is well illustrated with schematics prepared for this text to help in the understanding of key concepts. It will provide a basic understanding of today's polymer science for technical and engineering personnel not already familiar with the subject, and a convenient update and overview for materials scientists.

A complete guide to the textural characteristics of an international array of traditional and special foods It is widely recognized that texture has an intrinsic relationship to food preference. A full understanding of its functions and qualities is, therefore, of crucial importance to food technologists and product developers, as well as those working towards the treatment of dysphagia. Textural Characteristics of World Foods is the first book to apply a detailed set of criteria and characteristics to the textures of traditional and popular foods from across the globe. Structuring chapters by region, its authors chart a journey through the textural landscapes of each continent’s cuisines, exploring the complex and symbiotic relationships that exist between texture, aroma, and taste. This innovative text: Provides an overview of the textural characteristics of a wide range of foods Includes descriptions of textures and key points of flavor release Examines the relationships between the texture, taste, and aroma of each food presented Is structured by geographic region Rich with essential insights and important research, Textural Characteristics of World Foods offers all those working in food science and development a better picture of texture and the multifaceted role it can play.
