Abstract
Cotton linters, swelled cotton linters and carbamated cotton linters of dif ferent nitrogen content were followed by IR spectroscopy and thermal analys es. 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 a nd swelling. (C) 2000 Elsevier Science Ltd. All rights reserved.
