of complex polyolefins. It summarizes important applications in all major fractionation methods with emphasis on multidimensional analytical approaches. The
theoretical background, equipment, experimental procedures and applications are
discussed for each fractionation technique. It will enable polymer chemists,
physicists and material scientists, as well as students of polymer and analytical
sciences, to optimize experimental conditions for specific fractionation problems.
The main benefit for the reader is that a great variety in instrumentation, separation
procedures and applications is given, making it possible to solve simple as well as
sophisticated separation tasks.
The book is structured in a similar fashion to the review article of the authors. It
commences with a short introduction to the molecular complexity of polyolefins.
This is followed by a discussion of crystallization-based fractionation techniques,
including TREF, CRYSTAF and CEF. The major part addresses column chromatographic techniques for molar mass, chemical composition and microstructure,
and the combination of different fractionations in multidimensional experimental
set-ups. Finally, some first information on the application of field-flow fractionation
is presented.
This textbook is dedicated to friends and colleagues that contributed (directly or
indirectly) to this book by pioneering high temperature fractionation using HPLC,
TREF, CRYSTAF, CEF and multidimensional chromatography, most prominently
Tibor Macko (Germany) and, among others, Benjamin Monrabal (Spain), Freddy
van Damme (The Netherlands), Yefim Brun, Colin Li Pi Shan and Rongjuan Cong
(USA), Wolf Hiller, Robert Bruell, Dieter Lilge, Volker Dolle and Peter Montag
(Germany), Joao Soares (Canada), Albert van Reenen (South Africa) and a number
of former graduate students including Lars-Christian Heinz, Andreas Albrecht,
Nyambeni Luruli, Pritish Sinha, Tino Otte, Anton Ginzburg, Stefan de Goede,
Elana de Goede and Sadiqali Cheruthazhekatt.
