Abstract: A gas permeable polytetrafluoroethylene stretched film is prepared by bending powder of a modified polytetrafluoroethylene resin and powder of a modified fluoropolymer resin and stretching the powder of the modified polytetrafluoroethylene resin and the powder of the modified fluoropolymer resin. The modified polytetrafluoroethylene resin is copolymerised by mixing a tetrafluoroethylene monomer and a modified monomer. The modified monomer is prepared by reaction of hydroxyethyl acrylate, perfluoroalkylethyl acrylate and isocyanate ethylacrylate. The crystallinity in the system is greatly reduced through the multi-branched structure of the modified polytetrafluoroethylene polymer, and at the same time, the strenching strength of the gas permeable polytetrafluoroethylene stretched film is greatly improved through adding the modified fluoropolymer powder. In this manner, the polytetrafluoroethylene stretched film has strong permeability and waterproofness, thereby having stronger safety.
