US Patent:

20040138399, Jul 15, 2004
Filed:

Dec 16, 2003
Appl. No.:

10/473453
Inventors:

Iain MacKinnon - Penarth, GB
Pierre Chevalier - Penarth, GB
Duan Ou - Framingham MA, US
International Classification:

C08G077/12
US Classification:

528/031000
Abstract:

In a process for the preparation of a solution of a stable silicone resin comprising SiOunits and units selected from RSiO, RR′SiO, and RR′SiOunits, where R is an alkyl, alkenyl, substituted alkyl, cycloalkyl, aryl or aralkyl group imparting desired physical or chemical properties to the resin, for example a thermally labile group, and each R′ is a different alkyl, substituted alkyl, cycloalkyl, aryl or aralkyl group, or a hydrogen atom, a hydrosiloxane resin comprising HSiOunits and the said units selected from RSiO, RR′SiO, and RR′SiOunits is treated with a base to condense at least some of the HSiOunits to form SiOunits. The base is preferably a solution of an alkali metal salt of a weak acid, such as sodium acetate.
