This Springer Laboratory volume introduces the reader to advanced
techniques for the separation and fractionation of polyolefins. It
includes detailed information on experimental protocols and procedures,
addressing the experimental background of different polyolefin
fractionation techniques in great detail. The book summarizes important
applications in all major fractionation methods with emphasis on
multidimensional analytical approaches. It comprises the most powerful
modern techniques, such as high temperature size exclusion
chromatography (HT-SEC) for molar mass analysis, temperature rising
elution fractionation (TREF) and crystallization analysis fractionation
(CRYSTAF) for the analysis of chemical composition and branching, high
temperature two-dimensional liquid chromatography (HT-2D-LC), solvent
and temperature gradient interaction chromatography (SGIC and TGIC) and
crystallization elution fractionation (CEF). Beginners as well as
experienced chromatographers will benefit from this concise introduction
to a great variety in instrumentation, separation procedures and
applications. With detailed descriptions of experimental approaches for
the analysis of complex polyolefins, the readers are offered a toolbox
to solve simple as well as sophisticated separation tasks. The book
starts with an introduction into the molecular complexity of
polyolefins - the most widely used synthetic polymers with rapidly
growing production capacities. It systematically discusses
crystallization based fractionation techniques including TREF, CRYSTAF
and CEF and column chromatographic techniques for molar mass, chemical
composition and microstructure, as well as the combination of different
fractionations in multidimensional experimental setups. This book also
includes basic information on the application of high-temperature
field-flow fractionation.
