“…In this case, a greater variety of monomers have been grafted to chitosan via the grafted from procedure, for example, acrylic monomers [95,96,97,98,99,100,101,102,103,104,105,106,107,108,109,110,111,112,113], styrene [105], oligoethylene glycol methacrylate [114], N -vinyl-2-pyrrolidone [115,116], ε-caprolactone [36,37,116,117,118], lactide [119], urethane [120], indole [87], and aniline [121], among others. The types of polymerization and initiator to be employed depend on the selected monomer.…”
