Fluoroalkene copolymer

A method for producing a fluoroalkene copolymer, the method comprising producing a fluoroalkene copolymer having a structure represented by the following general formula (1) by subjecting a compound represented by the following general formula (2) and a compound represented by the following general formula (3) to radical polymerization,

• wherein R1, R2, and R3 are the same as defined above;
• x and y represent a proportion of each monomer contained (x+y=100(%), x and y are in ranges of 10≤x, y≤90), respectively;
• and a filled circle represents a bond,
• wherein R1 is a fluorine atom, a perfluoroalkyl group having 1 to 10 carbon atoms which may have —O— between carbon atoms, or a perfluoroalkoxy group having 1 to 10 carbon atoms which may have —O— between carbon atoms,
• wherein R2 and R3 each independently represent a hydrogen atom, a halogen atom, an aliphatic hydrocarbon group having 1 to 30 carbon atoms which may have a substituent, or an aryl group which may have a substituent;
• said R2 and R3 may be linked with each other to form a ring;
• and said aliphatic hydrocarbon group may contain one or more selected from the group consisting of —O—, —Si(CH3)2—, —CO—, and —NH— between carbon atoms.
