| Abstract: | Cotton linters, swelled cotton linters and carbamated cotton linters of different nitrogen content were followed by IR spectroscopy and thermal analyses. Crystallinity indexes of the swollen and carbamated cotton linters are lower than untreated cotton linters. The decomposition temperature is lower in the case of swelled and carbamated cotton linters than untreated ones. Also the rate constant of thermal treated samples decrease by carbamation and swelling. |
