Title:
FLUORORESIN AND METHOD FOR PRODUCING THE SAME
Document Type and Number:
Japanese Patent JP2021155735
Kind Code:
A
Abstract:
To provide a fluororesin having an oxolane ring, which is suppressed in yellowing after heating and melting and which is reduced in coloring especially in molding of a thick wall product.SOLUTION: Provided is a fluororesin which contains a residue unit represented by the following formula (1) and a terminal group formed of a specific perfluorinated C4-21 alicyclic hydrocarbon. (In formula (1), Rf1, Rf2, Rf3, and Rf4 each independently represent one selected from the group consisting of a fluorine atom, C1-7 linear perfluoroalkyl groups, C3-7 branched perfluoroalkyl groups, or C3-7 cyclic perfluoroalkyl groups. The perfluoroalkyl group may have an ethereal oxygen. Further, Rf1, Rf2, Rf3, and Rf4 may be linked to each other to form a C4-8 ring and the ring may be one containing an ethereal oxygen.)SELECTED DRAWING: None
