This book presents topical research in the study of the types, properties and applications of elastomers. Topics discussed in this compilation include elastomers for biomedical applications; elastomeric diffractive optics fabricated by soft lithography; optical spectra of chiral elastomers during segregation and elastic processes; the effect of brominated fire retardants on the properties of thermoplastic elastomers and interfacial interaction in blends of elastomers with different polarities.
