Recent advances in polymer science have made it possible to relate
quantitatively molecular structure to rheological behavior. At the same
time, new methods of synthesis and characterization allow the
preparation and structural verification of samples having a range of
branched polymeric structures. This book unites this knowledge to enable
production of polymers with prescribed processability and end-product
properties. Methods of polymer synthesis and characterization are
described, starting from fundamentals. The foundations of linear
viscoelasticity are introduced, and then the linear behavior of
entangled polymers is described in detail. This is followed by a
discussion of the molecular modeling of linear behavior. Tube models for
both linear and branched polymers are presented. The final two chapters
deal with nonlinear rheological behavior and tube models to describe
nonlinearity. In this second edition, each chapter has been
significantly rewritten to account for recent advances in experimental
methods and theoretical modeling. It includes new and updated material
on developments in polymer synthesis and characterization, computational
algorithms for linear and nonlinear rheology prediction, measurement of
nonlinear viscoelasticity, entanglement detection algorithms in
molecular dynamics, nonlinear constitutive equations, and instabilities.
