Abstract
A dispersion includes dispersed particles. The particles include a reaction product of a first polymer, a second polymer, and a chain terminator. The first and second polymers have at least two Si—H moieties and silicon bonded unsaturated moieties, respectively. The chain terminator has one Si—H moiety or one unsaturated hydrocarbon moiety. The first and second polymers and the chain terminator are reacted in the presence of a metal catalyst. The dispersion is formed by a method that includes the step of combining the first and second polymers, and the chain terminator. This method also reacts the first and second polymers and the chain terminator in the presence of the metal catalyst to form the dispersed particles.
