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