Zusammenfassung: | A method of preparing condensation cross-linked particles in an emulsion includes combining a first linear reactant having two unsaturated carbon-carbon moieties, a second linear reactant having two Si-H moieties, and a third reactant having at least one condensable reactive group and having up to two unsaturated carbon-carbon moieties or Si-H moieties with the proviso that the third reactant has at least one unsaturated carbon-carbon moiety or Si-H moiety. The first, second, and third reactants are combined in the presence of a hydrosilylation catalyst and a polar liquid to form an emulsion wherein the first, second, and third reactants react via a hydrosilylation reaction to form particles that have a linear backbone wherein the condensable reactive group is disposed thereon. The method also includes cross-linking the linear backbone via a condensation reaction to form the condensation cross-linked particles.
