US Patent 7244799 - Siloxane manufacturing using nanoparticle catalysts

http://www.freepatentsonline.com/7244799.html

Siloxanes are components of material such as synthetic rubber. This patent from Kansas State University is directed to a new method of making siloxanes using catalytic nanoparticles such that the siloxane can be formed with a nanostructured morphology. Claim 1 reads:

1. In a method of preparing siloxanes wherein a substituted silane is polymerized in an solvent system comprising water, the improvement which comprises carrying out said polymerization in the presence of an effective amount of a nanoparticle metallic catalyst.
