WebA siloxane is a functional group in organosilicon chemistry with the Si−O−Si linkage. The parent siloxanes include the oligomeric and polymeric hydrides with the formulae H (OSiH 2) n OH and (OSiH 2) n. [1] Siloxanes also include branched compounds, the defining feature of which is that each pair of silicon centres is separated by one ... WebThe degradation product dimethylsilanediol, in full accordance with expected hydrolytic degradation of silicone oil, increased during storage and with elevated temperature. In addition, the method can be applied to aqueous samples where polydimethylsiloxane has been added as, for example, the major constituent of antifoam. Keywords:
