Abstract: A process for preparing a cellulosic sponge includes the steps of treating an aqueous suspension of cellulose fibers with periodate; adjusting the pH of the resulting dialdehyde cellulose fibers suspension to a value between 2.5 to 5.5; freezing the suspension obtained and thawing the three dimensional structure to render the cellulosic sponge. The process may further include a step of drying to render a cellulosic foam. Both the new sponge and the new foam may also be further chemically modified obtaining a broad variety of derivatives with tailored properties which are useful in many different applications.

Abstract: Foams for filling cavities and crevasses and for forming foamed products are provided. The latex foam may include an A-side containing a functionalized latex and a B-side that contains a crosslinking agent and optionally a non-functionalized latex. The A- and/or B-side contain a blowing agent package or components forming the blowing agent package. The blowing agent package may be the combination of two or more chemicals that when mixed together form a gas or a chemical compound that, when activated by heat or light, forms a gas. In an alternate embodiment, the latex foam includes a functionalized latex, an acid, and an encapsulated crosslinking agent and base. Alternatively, the spray latex foam may include a functionalized latex, a crosslinking agent, and an encapsulated dry acid and dry base. The encapsulating agent may be a protective, non-reactive shell that can be broken or melted at the time of application.
