Abstract

1.- procedure for the preparation of porous partitions for batteries of accumulators of sulfuric acid, characterized in that in its execution it comprises the following operational stages: i) obtaining a sheet of fibrous material comprising: a) a mixture of fibers constituted by the 3 to 4% by weight of cellulosic fibrils and 97 to 60% by weight of fibrils of at least one thermoplastic polymer, with a surface area comprised between 3 and 15 m2/g; b) from 0.1 to 3% by weight, expressed as a fiber mixture, of an ionic wetting agent, dispersed homogeneously in the fibrous mixture; ii) heating the sheet to a temperature equal to or higher than the melting temperature of said thermoplastic polymer, carried out in the absence of pressure on the sheet, for a sufficient time to cause the fusion of the fibrils present in the sheet.
