It has been studied by NMR 13C, FTIR, UV and GPC the chemical structure and
molecular mass distribution of carbossimetilcellulose, obtained by homogeneous oxidation. It is
found that oxidized units of dialdehydcarbossimetilcellulose exists in the form of semiacetal
intramolecular bonded cycles. This structure has been registered both in solid state and in D2O
solutions. Controlled periodate oxidation resulted in subsequent reduction of molecular weight and
it is not resulted in cross-linking of the polymer.
