Standard Test Method for Determination of the Degree of Unsaturation of Butyl Rubber by FTIR and Multivariate Analysis

Importancia y uso:

5.1 This infrared absorbance method quantifies the total unsaturation structures in butyl rubber using the characteristic infrared absorbance regions and multivariate analysis. This method accounts for superimposing absorbances and is an extension of the typical method for infrared quantification, which correlates a single band absorbance height or area with concentration. This method measures the level of total unsat¬uration in butyl rubber by multivariate analysis Fourier Transform Infrared Spectroscopy. It is applicable for butyl rubber in the concentration range of 1.00 to 2.40 mol%. It can be expanded beyond these ranges with additional calibration RMs.
