Abstract
The present invention provides a novel copolymer of 2,3,3,3-tetrafluoropropene and a non-fluorinated ethylenic hydrocarbon monomer. The copolymer contains (A) a 2,3,3,3-tetrafluoropropene unit and (B) a non-fluorinated ethylenic hydrocarbon monomer unit. The copolymerization ratio (mol % ratio) of (A) and (B) is 99.9:0.1 to 0.1:99.9 and the number average molecular weight of the copolymer is 1000 to 1000000.
