Hydrolysis of poly(dimethylsiloxanes) on clay minerals as influenced by exchangeable cations and moisture

Article Abstract:

The hydrolysis of poly(dimethylsiloxanes) (PDMS) fluid on clay minerals has been found to be dependent on exchangeable cation type, moisture level and clay type. Determinants of PDMS hydrolysis are also found to be the determinants of degradation rates and products of silicone polymers in the siad reaction. The scission of the PDMS' Si-O-Si backbone was the predominant factor in the hydrolysis reaction.
