FLUORINE-CONTAINING ELASTIC COPOLYMER, COMPOSITION THEREOF, AND CROSSLINKED RUBBER ARTICLE

Title:

FLUORINE-CONTAINING ELASTIC COPOLYMER, COMPOSITION THEREOF, AND CROSSLINKED RUBBER ARTICLE

Document Type and Number:

WIPO Patent Application WO/2019/009248

Kind Code:

A1

Abstract:

Provided are: a fluorine-containing elastic copolymer which has rubber properties sufficient for practical applications and with which a crosslinked rubber article having excellent low-temperature characteristics can be obtained; a fluorine-containing elastic copolymer composition; a crosslinked rubber article; and a method for producing a fluorine-containing elastic copolymer. The fluorine-containing elastic copolymer has a unit based on tetrafluoroethylene, a unit based on CF2=CFORf1 (Rf1 is a C1-10 perfluoroalkyl group), a unit based on CF2=CF(OCF2CF2)n-(OCF2)m-ORf2 (Rf 2 is a C1-4 perfluoroalkyl group, n is an integer of 0-3, m is an integer of 0-4, and n+m is an integer of 1-7), and a unit based on a fluorine-containing monomer having two or more polymerizable unsaturated bonds.
