International Classification:

B01D 11/00

US Classification:

210634, 210640, 210660, 210690

Abstract:

The present invention relates generally to hybrid organic-inorganic adsorbents for decontamination of fluids. Bridged poysilsesquioxanes are a family of hybrid organic-inorganic materials prepared by sol-gel processing of monomers that contain a variable organic bridging group and two or more trifunctional silyl groups. Specifically, the present invention relates to dipropylenedisulfide-co-phenylene-bridged polysilsesquioxane compositions, methods of making dipropylenedisulfide-co-phenylene-bridged polysilsesquioxanes, and methods of use of dipropylenedisulfide-co-phenylene-bridged polysilsesquioxanes. The present invention discloses properties of dipropylenedisulfide-co-phenylene-bridged polysilsesquioxanes that include high ligand loading, increased surface area, and increased porosity. These properties make dipropylenedisulfide-co-phenylene-bridged polysilsesquioxanes excellent adsorbents for decontamination of fluids for use in environmental and industrial processes.

US Classification:

528 4

Abstract:

Living polymer synthesis methods for the synthesis of oligomeric and high molecular weight polymers with low polydispersity are disclosed. The disclosed methods are based on the discovery that the reaction of a ylid with an organoborane at a high ylid:borane ratio and high temperature provides for the synthesis of high molecular weight polymers with low polydispersity.
