Study on Endogenous Sugar Structure and Thermal Denaturation of Natural Rubber
The endogenous sugar structure of natural rubber was studied by mid-infrared(MIR)spectroscopy.The variable temperature deconvolution MIR spectra of endogenous sugar structures was studied by variable temperature MIR spectroscopy.The structural thermal denaturation of endog-enous sugars was studied by 2 D MIR spectroscopy.The results showed that in the range of 293 K～393 K,the absorption wave number corresponding to the endogenous sugar crystal structure changed significantly with the increase of the test temperature.There were significant differences in the thermal sensitivity of endogenous sugar structure and the speed order of functional group change.Under ther-mal disturbance factors,the change of endogenous sugar crystal structure was a key step in the entire endogenous sugar structure change.
