Chapter
Synthetic polymers are multicomponent complex systems having overlap** distributed properties. This chapter focuses on description of these overlap** distributions of molecular properties such as molar mas...
Chapter
In order to assess the distribution of their molecular properties, polymers must be separated. This book is devoted to the methods of polymer separations in solution. This chapter is intended to provide basic ...
Chapter
This chapter provides the basic concept of entropy/enthalpy compensation phenomenon operative in polymer LC. History of the development of the methods based on entropy/enthalpy compensation is followed by spec...
Chapter
LCLC is another approach to exploit the phenomenon of entropy/enthalpy compensation. The methods are broadly categorized as “barrier methods”. The working principle based on the nature of the eluent and barrie...
Chapter
The final chapter of the book summarizes the strengths and limitations of different methods of LC of polymers. Still existing challenges and opportunities are highlighted.
Chapter
This chapter is devoted to the polymer LC methods, in which the processes of permeation and exclusion of macromolecules into/from the porous column packing particles play a decisive role. For obvious reasons, ...
