摘要: A method (500) for conditioning or hydrolysis of an extruded membrane is disclosed.
The method (500) comprising ion exchange processes in divided electrochemical cells using a cation exchanger membrane. The method (500) includes extruding the perfluorosulfonyl fluoride membranes from perfluorosulfonyl fluoride granulate. The method (500) also includes using a pretreatment technique to increase the ionic conductivity of the extruded perfluorosulfonyl fluoride membranes before using the perfluorosulfonic acid membranes in electrolysis cells. The method (500) also includes applying a milder pretreatment technique by activating S-F bonds to execute nucleophilic exchange of the fluoride group in a reaction. The method (500) also includes hydrolyzing sulfonyl fluoride groups to sulfonic acid using triethylsilanol.-

摘要: A method for obtaining low molecular weight polytetrafluoroethylene (PTFE) comprising the following steps: provision of high molecular weight PTFE; arrangement of said high molecular weight PTFE in a chamber, delimited by a gas barrier and containing a controlled atmosphere with an amount of oxygen comprised from 0.005% to 0.5% by volume; hermetically sealing of said chamber containing said high molecular weight PTFE; irradiating said PTFE into said hermetically sealed chamber to obtain said low molecular weight PTFE.
