A novel glycol-silicone polymer

A novel glycol-silicone polymer

The reaction between ethylene glycol and Me sub 2 SiCl sub 2 was examined. Under the conditions used, a dimeric ring was obtained in addition to traces of a monomeric species. In contrast, the reaction under identical conditions between MeHSiCl sub 2 and ethylene glycol led to a gel, clearly a polym...

Zusammenfassung:The reaction between ethylene glycol and Me sub 2 SiCl sub 2 was examined. Under the conditions used, a dimeric ring was obtained in addition to traces of a monomeric species. In contrast, the reaction under identical conditions between MeHSiCl sub 2 and ethylene glycol led to a gel, clearly a polymer. Synthetic and structural studies of this polymer have shown it to be a crosslinked glycol--silicon polymer containing both disiloxane and glycol--siloxane components. 15 ref.--AA
