Abstract The addition products of some monochlorosilanes to methyl oleate and undecanoate were hydrolyzed and condensed to yield the corresponding difunctional disiloxanes, which were, inturn, transformed by alkaline hydrolysis or reduction to the corresponding diacids or diols. The addition products of dichlorosilanes gave on hydrolysis and condensation cyclosiloxanes but not linear polymers, as shown by mol wt data and IR spectra, while the corresponding addiiton products of trichlorosilances gave on similar treatment rubbery cross‐linked polymers. In contrast to the silanol intermediates, obtained on hydrolysis of methylchlorosilanes, which condensed easily to the corresponding disiloxanes, the corresponding bulkier phenyl chlorosilanes gave stable silanols which showed a lower tendency to condense. Some mono‐and di‐alkoxy, phenoxy, and acetoxy silyl derivatives of the long chain fatty acid esters also were synthesized.
