| titleOfInvention | Production of porous membrane of ethylene-tetrafluoroethylene copolymer |
| abstract | PURPOSE: To produce the titled porous membrane having excellent heat- resistance and filtration property, by mixing inorganic fine powder and a chlorotrifluoroethylene oligomer to an ethylene-tetrafluoroethylene copolymer, melting and forming the mixture, and extracting the inorganic fine powder and the oligomer from the formed article. n CONSTITUTION: (A) 10W60(vol)% ethylene-tetrafluoroethylene copolymer is mixed with a mixture of (B) 7W42% inorganic fine powder which is fine particles or porous particles having a specific surface area of 50W500m 2 /g and an average primary particle diameter of 0.005W0.5μ, preferably fine silica and (C) 30W75% chlorotrifluoroethylene oligomer (preferably 4W15-mer) or a mixture of said oligomer and other heat-resistant organic substance having an sp value of 5W11 (preferably silicon oil). The obtained mixture is formed under melting, and the component C and then the component B is extracted from the formed article to obtain a porous membrane of the component A having uniform porous structure. n COPYRIGHT: (C)1986,JPO&Japio |
