By: Boyd, Richard H. (Richard Hays), 1929- [author.].
Contributor(s): Smith, Grant D [author.].
Material type: materialTypeLabelBookPublisher: Cambridge : Cambridge University Press, 2007Description: 1 online resource (x, 255 pages) : digital, PDF file(s).Content type: text Media type: computer Carrier type: online resourceISBN: 9780511600319 (ebook).Other title: Polymer Dynamics & Relaxation.Subject(s): Polymers | Polymers -- Structure | Molecular dynamicsAdditional physical formats: Print version: : No titleDDC classification: 547.7 Online resources: Click here to access online
Contents:
Methodology -- Mechanical relaxation -- Dielectric relaxation -- NMR spectroscopy -- Dynamic neutron scattering -- Molecular dynamics (MD) simulations of amorphous polymers -- Amorphous polymers -- The primary transition region -- Secondary (subglass) relaxations -- The transition from melt to glass and its molecular basis -- Complex systems -- Semi-crystalline polymers -- Miscible polymer blends -- Appendix AI : the Rouse model -- Appendix AII : site models for localized relaxation.
Summary: Polymers exhibit a range of physical characteristics, from rubber-like elasticity to the glassy state. These particular properties are controlled at the molecular level by the mobility of the structural constituents. Remarkable changes in mobility can be witnessed with temperature, over narrow, well defined regions, termed relaxation processes. This is an important, unique phenomenon controlling polymer transition behaviour and is described here at an introductory level. The important types of relaxation processes from amorphous to crystalline polymers and polymeric miscible blends are covered, in conjunction with the broad spectrum of experimental methods used to study them. In-depth discussion of molecular level interpretation, including atomistic level computer simulations and applications to molecular mechanism elucidation, are discussed. The result is a self-contained approach to polymeric interpretation suitable for researchers in materials science, physics and chemistry interested in the relaxation processes of polymeric systems.

Polymers exhibit a range of physical characteristics, from rubber-like elasticity to the glassy state.

Remarkable changes in mobility can be witnessed with temperature, over narrow, well defined regions, termed relaxation processes. This is an important, unique phenomenon controlling polymer transition behaviour and is described here at an introductory level. The important types of relaxation processes from amorphous to crystalline polymers and polymeric miscible blends are covered, in conjunction with the broad spectrum of experimental methods used to study them.
