(organic chemistry)
R2SiO Any of a family of silica-based polymers in which R is an alkyl group, usually methyl; these polymers exist as oily liquids, greases, rubbers, resins, or plastics. Also known as oxosilane.



any of the compounds containing the grouping

Siloxanes are anhydrides of silicon acids. Organosiloxanes (seeORGANOSILICON COMPOUNDS) and polyorganosiloxanes (seeSILICONES) are the most important of these compounds. [23–1092–]

The improved retention of impact at a higher temperature (130[degrees]C) than at a lower temperature (120[degrees]C) for the BPAPC-PDMS samples could be due to changes in the morphology, especially due to an increase in the size of siloxane domains at 130[degrees]C via aggregation of siloxane domains which may not be happening at 120[degrees]C.
