Abstract
A method for preparing a porous plate of thermoplastic resin, comprising the following operations: kneading the resin with 20-90% by weight of particles of a material selected from a group comprising: calcium sulfate, calcium sulfite and mixtures therebetween ; forming a plate with the resulting kneaded mixture and immersing it in an aqueous solution of an inorganic acid selected from a group consisting of hydrochloric and nitric acid, and dissolving said particles from the plate to obtain a porous plate.
