Investigation of the reaction between oligo-oxyethylene urethane methacrylates and ozone in order to determine double bonds

Abstract

fact tha t with an increase m the degree of drying, the absorbed is characterized by a stronger H bond with cellulose molecules. As K ~ is the ratio of absorption coefficients for bond-stretching and deformation vibrations of the OH bond of water, on increasing chsturbance due to the H bond, the increase m the absorption coefficient for bond-stretching mbrations is less than for deformation vlbrahons. According to modern views of the structure of cellulose, the disordered region is characterlzed by varying abili ty to absorb moisture, Le. one can talk about a set or spectrum of disordered regions of cellulose Cellulose materials of different origin are characterized both by a different water surface [5] and different heats of wetting. The constancy of K~i t values according to moisture content m further evidence of the heterogeneity of cellulose m dmordered regions. CONCLUSIONS
