Abstract

Microporous material is made by producing a mixture of a swellable plastic, a volatile swelling agent and a granular material, the structure of which is unaffected by the swelling agent, swelling the plastic, shaping to the required form and removing the swelling agent by evaporation. Polyvinyl chloride is the specified plastic, trichlorethylene and benzene the swelling agents and wood flour, lignin and kaolin, the granular material. It is preferred that the material is shaped to form porous plates.
