Quantitative Analysis of the Content of Substituent Group in Difunctional Polysiloxane

Abstract:

In the present work, a new method for the analysis of the substituent group content in silicones by automatic elemental analyzer has been developed. Because of the number of substituent group effect on the physical and chemical properties about polysiloxane very much, its analysis by traditional techniques is tedious and costly. The novelty of this study relies on the fast and universal application of the automatic elemental analyzer to the quantitative analysis of the substituent groups. With this purpose, analysis of the quality percentage content of C and H in four different kinds of difunctional polysiloxane in automatic elemental analyzer, then compute the formula weight of a basic structure unit to deduce the content of the substituent group. The result was validated by 1H NMR.
