摘要: The models of structural organization cellulose are reviewed within the framework semi-crystalline concept. Special attention is given to two crystalline modifications cellulose: Iα and Iβ. results low-resolution 1H NMR studies supramolecular structure considered. mathematical model describing line shape solid-state spectrum presented. A scheme for microfibrils that fits most known concepts proposed. It shown this can be used determine major parameters polymer.
