POLYSILOXANES COMPRISING METHYLENE-BONDED POLAR GROUPS

Organopolysiloxanes containing a large proportion of methylene-bonded polar groups have high relative permittivities, and are especially useful as thermally stable dielectrics. A methoxymethyl alkoxysilane starting material is easily synthesized, and can be incorporated into the polymers by conventi...

Beschreibung
Zusammenfassung:	Organopolysiloxanes containing a large proportion of methylene-bonded polar groups have high relative permittivities, and are especially useful as thermally stable dielectrics. A methoxymethyl alkoxysilane starting material is easily synthesized, and can be incorporated into the polymers by conventional methods known in organosilicon chemistry.
