Polymeric gel composition and method for making

摘要

An anhydrous gel composition is provided for holding and dispersing into the surrounding air space, in a time controlled manner, a volatile composition contained within the gel. The gel composition is formed by crosslinking a polymer solution that contains the volatile composition. In one embodiment the gel composition comprises about 8% to about 25% by weight of an anhydride functionalized polymer; about 0.3% to about 10% by weight of total crosslinker reagent; and about 50% to about 90% by weight of a functional volatile component.
