This volume is based on lectures given at the NATO-Advanced Study
Institute on Structure and Dynamics of Polymer and Colloid Systems
held in Les Houches, France from September 14-24, 1999. The meeting
arose from a perceived need to bring together scientists studying
the polymer and colloid fields. Although these fields are
intertwined and share many techniques (e. g. , light, neutron and
x-ray scattering), it is remarkable how little the approaches and
concepts used by the one field penetrate the other. For instance,
the theory of spherical colloids is very highly developed and many
of the concepts developed for these systems can be extended to
those with non-spherical morphology, such as solutions of rigid rod
polymers. In addition, mixtures of polymers and colloids, both in
the bulk and at interfaces, are the basis for many industrial
products. Methods are now rapidly being developed for understanding
the structure and dynamics in polymer/colloid mixtures at the
molecular level, but the point of view of the colloid scientist is
often rather different from that of the polymer scientist. The
NATO-ASI brought together polymer and colloid scientists, including
many young researchers, who presented and discussed recent
developments in these fields and the possibilities for
cross-fertilization This volume contains articles on a wide variety
of topics at the research forefront of the polymer and colloid
fields by some of the world's foremost experts at a level
accessible to graduate students, post-docs and researchers.

This book reports the preparation and characterization of new
rod-coil amphiphiles functionalized with oligo- and polysaccharides
through Huisgen 1,3-dipolar cycloaddition reactions between species
functionalized by an azide group on one side and an terminal alkyne
on the other catalyzed by copper. The amphiphiles were synthesized
and characterized based on different hydrophobic parts conjugated
with the polymer poly(ethylene oxide) PEO with a hydrophilic spacer
arm and the oligo- and polyssaccharides 2-propargyl-2-acetamido-
2-deoxy- -D-glucopyranose (GlcNAc) and propargyl
-D-galactopyranosyl-(1-4)- -D-glucopyranose (Lac). The amphiphiles
synthesized were characterized in terms of their chemical structure
and composition through nuclear magnetic resonance (NMR), mass
spectroscopy (MALDI-TOF-MS and ESI-MS)and high resolution mass
spectroscopy (HRMS). After the dissolution in water, the
amphiphiles self-associate in highly regular micelles with an
average diameter of 2RH 10nm. Dynamic light scattering (DLS),
transmission electron microscopy (TEM) and small angle x-ray
scattering (SAXS) were used in order to investigate the structure
and dynamics of these saccharide amphiphiles."
