The system is composed of polysilicic ions and polyaluminous ions with the participation of polyaluminous ions, the Si-O specific line which is inherent in the examination of infrared spectrum is gradually reducing and becoming a broad belt, the non-ion bond reactions between polysilicic ion and polyaluminous ion is proved by observasion with electron microscopy.

The stability of polydimethylsiloxane cationic emulsions towards electrolytes wasstudied.
