Polysiloxane with covalently attached undecanoic acid groups was obtained in a two-step synthesis. Four molecules of methyl undec-10-enoate were attached to 1,3,5,7-tetramethylcyclotetrasiloxane (D4H) by hydrosilylation reaction yielding a new monomer, tetra(l 1-methoxy-l l-oxoundecyl)tetramethyl-cyclotetrasiloxane . The monomer was polymerized using anionic ring opening polymerization with concomitant hydrolysis of ester bonds. The silicone polymer thus obtained can self-organize in aqueous environment forming large objects, probably vesicles, with diameter of 1 pm. Silicon nanocapsules of controlled size can be prepared in a simple way in the polymerization processes of Dj""1*"'1 within vesicle templates. The monomer swells the surfactant vesicles up to 50 mol % based on the surfactant. Polymerization of D4"IK,"yl inside membrane yields nanocapsules of size similar to the originate vesicles.
