Paper Abstract

By IR spectroscopy methods the structural changes of high molecular polymers irradiated by CW CO2-laser radiation was investigated. Some changes in the structural sensitive regions at 1250 - 950 and 950 - 850 cm-1 of the IR spectra of the investigated polysaccharides [pullulan (molecular mass of 14500) and microcrystalline cellulose (structural modifications I and II)] were exhibit. These changes indicated that the degree of conformational order of polysaccharide molecules increases under the laser irradiation, while its structural order always decreases as a result of heating by traditional thermal sources.
