    Abstract: A method for preparing a porous fluoropolymer precursor includes combining a fluoropolymer and a removable additive to form a composition, the removable additive having a thermal decomposition temperature greater than a sintering temperature of the fluoropolymer, compressing the composition to form a preform, and sintering the preform to form the porous fluoropolymer precursor. A method for preparing a porous fluoropolymer includes disposing the porous fluoropolymer precursor in a removing agent, contacting the removable additive with the removing agent, and removing, by the removing agent, the removable additive from the porous fluoropolymer precursor to form the porous fluoropolymer, wherein the porous fluoropolymer comprises a plurality of pores formed by removing the removable additive.

    Abstract: A method of making a material which comprises a filler and/or fugitive compound involves forming a layer L1 of a composition comprising a polymeric material and a filler material on a substrate; subjecting the layer L1 to a temperature to melt the polymeric material; formingon layer L1,a layer L2 of a composition comprising a polymeric material and a filler material; subjecting layer L2 to a temperature above the melting temperature of the polymeric material; and continuing forming layers as aforesaid as required. Subsequently, the material prepared may be removed from the substrate and/or the fugitive material may be removed, thereby to define a porous material which may be machined or otherwise further processed to produce medical implants or parts thereof.

    Abstract: PROBLEM TO BE SOLVED: To provide a sponge cloth based on cellulose and having an internal reinforcement in the form of a net or grid, the sponge cloth further including a uniform distribution in the sponge cloth of fibers and/or permanently softening polymers not water-leachable.SOLUTION: The sponge cloth is produced by the viscose process by mixing with the fibers and/or the softening polymers and the pore former with cellulose xanthate and forming the resulting sponge cloth raw material into a thin layer. The grid or net is placed onto this layer, followed by a further layer of the sponge cloth raw material. Alkaline or acidic coagulation and regeneration baths and wash baths are used to dissolve the pore former out of the sponge cloth and regenerate the cellulose from the cellulose xanthate. The sponge cloth is bend-resistant, it does not break in the dry state. The sponge cloth is envisioned for cleaning and decontamination in industry and the home.
