Regenerated perfluoro (CO)polymer production method and regenerated material production method

Heat-treating crosslinked perfluoro(co)polymers in an inert gas atmosphere regenerates crosslinking sites, addressing the recycling challenges of fluoroelastomers, resulting in recycled materials with properties comparable to virgin products for semiconductor applications.

Abstract

[Problem] To provide a method for producing a regenerated perfluoro (co)polymer wherein the crosslinking site of a crosslinked perfluoro (co)polymer that has been crosslinked is regenerated, the regenerated perfluoro (co)polymer production method making it possible to sufficiently regenerate a crosslinking site using a simple method while preventing a reduction in the mass of the perfluoro (co)polymer when regenerating the crosslinking site. [Solution] A regenerated perfluoro (co)polymer production method including a step for heat-treating, in an inert gas atmosphere, a crosslinked perfluoro (co)polymer obtained by crosslinking a perfluoro (co)polymer having a crosslinking site, and thereby regenerating the crosslinking site.
