ABSTRACT:
Open-cell foamed particles and molded shapes having up to 99% porosity are formed from fumed oxides, for example SiO.sub.2, Al.sub.2 O.sub.3, TiO.sub.2, with or without functional groups, in 30-99%, by weight, and polymers, for example polyvinyl chloride and copolymers thereof, and styrene. The resulting structures are thermally insulating. The structures can be formed by beating small amounts of a liquid polymerizable monomer into the fumed oxide or by immersing a formed shape of the oxide in a liquid monomer and thereafter polymerizing the monomer to a solid polymer. The oxide is believed to have a microfibrous nature and the polymer is believed to coat the oxide, without destroying the open-nature configuration of the oxide, and cements the oxide particles together in the microfibrous condition.
