Epoxy resins are regarded as thermosetting resins and have found various c- mercial applications after crosslinking with adequate curing agents [1-3]. H- ever, some epoxy resins have been used as thermoplastic resins without curing agents. Figure 1 shows the applications of epoxy resins that are classi?ed to three categories: thermosets in combination with curing agents, thermoplastics wi- out curing agents, and raw materials for modi?cation. The use in thermoplastics is not popular compared with the two other applications. Typical thermoplastic applications are found in stabilizers for vinyl resins, toners for copying - chines, ?re retardants for engineering plastics, and sizing material for glass or carbon ?bers. The epoxy resin most frequently used is the oligomer of the diglycidyl ether of bisphenol-A (DGEBA) whose chemical structure is shown below [1-3]. The DGEBA is composed of linear molecules with different molecular weights according to the variation of the repeated number (n) in the structural formula.

This book provides an introduction to this exciting and relatively new subject with chapters covering natural and synthetic polymers, colloids, surfactants and liquid crystals highlighting the many and varied applications of these materials. Written by an expert in the field, this book will be an essential reference for people working in both industry and academia and will aid in understanding of this increasingly popular topic. * Contains a new chapter on biological soft matter* Newly edited and updated chapters including updated coverage of recent aspects of polymer science.* Contain problems at the end of each chapter to facilitate understanding
