Abstract

Particles are prepared in an emulsion using a method that includes providing a first reactant having at least two unsaturated carbon-carbon moieties and a second reactant having at least two Si—H moieties, so long as at least one of the unsaturated carbon-carbon moieties of the first reactant or the Si—H moieties of the second reactant is pendant. The method also includes providing a third reactant having a silicon atom and a condensable reactive group bonded to the silicon atom and also having an unsaturated carbon-carbon moiety and/or a Si—H moiety, providing a hydrosilylation catalyst, and providing a polar liquid. The method further includes combining the first, second, and third reactants to form particles that have a cross-linked network wherein the condensable reactive group is disposed on the particles, and adding a silane having an organic moiety and a condensation leaving group to form the particles.
