Abstract
Official abstract text for this publication.
Materials for decontamination of compounds having a phosphorous-sulfur bond or a phosphorous-oxygen bond. A porous polymer, such as poly(dicyclopentadiene), contains particles of zirconium hydroxide. The polymer optionally has hydroperoxide groups.
First claim
Opening claim text (preview).
What is claimed is: 1 . A composition comprising: particles comprising zirconium hydroxide; and a polymer comprising hydroperoxide groups. 2 . The composition of claim 1 , wherein the polymer comprises pores. 3 . The composition of claim 2 , wherein the pores are produced by high internal phase emulsion templating. 4 . A method comprising: providing the composition of claim 1 ; and exposing the composition to a gas suspected of comprising a compound having a phosphorous-sulfur bond or a phosphorous-oxygen bond. 5 . The method of claim 4 , wherein the compound is O,O-diethyl S-2-(ethylsulfanyl) ethyl phosphorothioate, 2-chloroethyl ethyl sulfide, or ethyl ({2-[bis (propan-2-yl) amino] ethyl} sulfanyl) (methyl) phosphinate. 6 . A method comprising: providing an emulsion comprising: a monomer; particles comprising zirconium hydroxide; and water; polymerizing the monomer to form a porous polymer embedded with the zirconium hydroxide particles; and exposing the polymer to oxygen to form hydroperoxide groups on the polymer.
