- Abstract
- This paper contains new views about the amorphous and partially ordered phases of the three polymers
listed in the title. The discussion is based on information on structure, thermodynamic stability, and
large-amplitude molecular motion. Polyethylene is the basic backbone of all alkene polymers, and the
other two are the first members of the vinyl polymers which have stereospecifically placed alkyl side
chains. Their multiphase structures consist of metastable crystals, mesophases, and surrounding rigid
and mobile amorphous fractions. All these phases have sizes ranging from micrometer dimensions down
to nanometers. Besides the phase structures, information about the molecular coupling between the
phases must be considered. Depending on temperature, the polymer phases can vary from solid (rigid) to
liquid (mobile). New knowledge is also gained by cross-comparison of the title polymers. The experimental
information was gained from (a) various forms of slow, fast, and temperature-modulated thermal
analysis to identify equilibrium and non-equilibrium states, (b) measurement of structure and
morphology at various length scales, and (c) tracing of the large-amplitude molecular motion, the
kinetics of order/disorder changes, and the liquid/solid transitions (glass transitions). It is shown that
much more needs to be known about the various phases and their coupling to characterize a given
polymer and to fine-tune its properties for a given application. (literal)
