Resumen:
ith increasing emphasis on environmental care
and use of renewable resources, simple and effective dendronization
processes were performed to obtain chitosan derivatives. We
present different alternatives for the modification of chitosan:
dendronization with a biocompatible dendron; a quaternization
process with an ammonium salt, which confers a permanent
positive charge to the polymer; and a combination of methodologies
allowing amphiphilic polymers. This process confers
unique multivalent properties to the native chitosan, and further
modifications reach multivalent water-soluble polymers. Hence,
the most important highlight of this work is the use of renewable
natural polymers and the different methodologies applied to nontoxic solvents with low temperatures. The process described in
this paper represents a sustainable alternative for obtaining a functionalized material with properties suitable for application in
different areas, such as biomedicine or environmental re
