Updating his groundbreaking handbook to reflect advances made since the first edition was published, Charles Hansen invited five renowned experts to share their innovative work in this second edition. With a comprehensive look at the field, this updated and expanded edition surveys the theoretical and practical aspects of Hansen solubility parameters (HSP). New material discusses the use of statistical thermodynamics to confirm the division of cohesive energy into three parts, how HSP fits into other theories of polymer solutions, thermodynamic treatment of carbon dioxide, environmental stress cracking, and absorption and diffusion in polymers. All existing chapters feature revisions and updates where necessary.
