ABSTRACT:
A method of preparing a porous sheet product which comprises the step of introducing a spinning liquid comprising an organic fibre forming polymeric material into an electric field whereby fibres are drawn from the liquid to an electrode and collecting the fibres so produced upon the electrode. PTFE and other fluorinated polymer mats produced by the electrostatic process are useful as electrolytic cell diaphragms, battery separators etc.
