| titleOfInvention | Improved process for forming a thin microporous sheet material |
| abstract | A process for forming a microporous body having improved uniformity and permeability in which a normally solid or highly viscous polymeric reactive material is heated to bring it to a freely fluid state, a liquid having no or only very limited solvent or swelling action on the polymeric material is dispersed to form an emulsion with the polymeric material as the continuous phase, the polymeric material is reacted to tough, solid, resilient, film-forming condition, the emulsion is solidified and the liquid is removed leaving spaces constituting openings or pores in the solidified material. Where thin cross section bodies are desired, the emulsion is formed into a thin layer on a casting surface with a cover on the face of the emulsion opposite the casting surface, the cover remains in place during solidification of the emulsion, and is separated from the solidified emulsion before removal of the liquid. |
