Examples of ionomers include polystyrenes, polyurethanes, polyacrylics and certain glasses. This book relates the molecular architecture and morphology of ionomers with their physical properties and applications, including, for example, the glass transition, mechanical properties of random styrene-based and other ionomers. This reference offers a brief discussion of materials with special architectures, such as blocks and telechelics, and concludes with a discussion of ionomer blends, applications, and unsolved problems.
