Polyurethanes as Specialty Chemicals presents a different approach to polyurethane chemistry by examining a range of new products and new research for both environmental and medical applications

Features:

• Provides an overview of polyurethane chemistry including design tools for new products
• Presents the most current research on both medical and environmental remediation applications
• Presents polyurethane as a specialty chemical rather than a commodity foam or elastomer
• Combines the physical structure of polyurethane and its manipulation for achieving specific design objectives.
• Offers new procedures for design of new molecules as opposed to review applications
