METHOD FOR MANUFACTURING CROSSLINKED FLUOROPOLYMER

摘要

PROBLEM TO BE SOLVED: To obtain a crosslinked fluoropolymer improved in mechanical properties in a high temperature region. SOLUTION: The method for manufacturing a crosslinked fluoropolymer comprises crosslinking a perfluoropolycyano-alicyclic compound having at least two cyano groups by a trimerization reaction of the cyano group. Preferably, the perfluoropolycyano-alicyclic compound is a perfluorocycloalkane having 2-3 cyano groups.
