Abstract
New anionic amphiphilic thermosensitive pullulan derivatives have been synthesized through reaction of carboxymethylpullulan (CMP) with two Jeffamine® differing by their molecular weight (Jeff M2005 and Jeff M600). The structure of the derivatives was confirmed through FTIR and 1H NMR spectra. Their physico-chemical behavior has been studied through viscometric, fluorescence measurements, which evidenced the amphiphilic, thermosensitive character of these derivatives. The physico chemical characteristics of the synthesized pullulan derivatives depend on the Jeffamine used and on the degree of substitution with Jeffamine units introduced.
