    摘要： Provided are novel methods for producing a fluoropolymer. The disclosure relates to a method for producing a fluoropolymer by solution polymerization or dispersion polymerization, the method including: in the presence of an initiator, a chain transfer agent, and a solvent, (i) homopolymerizing tetrafluoroethylene; or (ii) randomly copolymerizing tetrafluoroethylene and at least one of a monomer represented by the following formula (1) or a monomer represented by the following formula (2),
    the chain transfer agent including at least one selected from the group consisting of dithioester compounds, dithiocarbamate compounds, trithiocarbonate compounds, and xanthate compounds, the fluoropolymer containing 50 to 100 mol% of a polymerized unit based on the tetrafluoroethylene,

            the formula (1):     CF 2 =CR 1 R 2

    wherein R 1 is H or F; R 2 is -Cl, -R a , -COOR b , -OCOR c , -CONR d 2 , -CN, -COR e , or -Rf a ; R a , R b , R c , R d , and R e are the same as or different from each other and are each H or a substituent; Rf a is the same as or different from each other and is an optionally substituted fluorine-containing alkyl group, an optionally substituted fluorine-containing vinyl group, or an optionally substituted fluorine-containing alkoxy group, each group optionally containing an oxygen atom between carbon atoms; and R 1 and R 2 optionally bind to each other to form a ring,

            the formula (2):     CH 2 =CR 3 R 4

    wherein R 3 is R g , CF 3 , or F; R 4 is -Cl, -R h , -COOR i , -OCOR j , -CONR k 2 , -CN, -COR m , or Rf c ; R g and R h are the same as or different from each other and are each H, an optionally substituted hydrocarbon group, or an optionally substituted heterocyclic group; R i , R j , R k , and R m are the same as or different from each other and are each H or a substituent; Rf c is the same as or different from each other and is an optionally substituted fluorine-containing alkyl group, an optionally substituted fluorine-containing vinyl group, or an optionally substituted fluorine-containing alkoxy group, each group optionally containing an oxygen atom between carbon atoms; and R 3 and R 4 optionally bind to each other to form a ring.

    摘要： The invention provides a novel sulfonic acid or carboxylic acid containing a carbonyl group, or a salt thereof. The compound of the invention is represented by the following formula:

            R 1 -C(=O)-(CR 2 2 ) n -(OR 3 ) p -(CR 4 2 ) q -L-A

    wherein
    R 1 is a linear or branched alkyl group containing one or more carbon atoms and optionally containing a substituent or a cyclic alkyl group containing three or more carbon atoms and optionally containing a substituent;
    R 2 and R 4 are each individually H or a substituent;
    R 3 is a C1-C10 alkylene group optionally containing a substituent;
    n is an integer of 1 or greater;
    p and q are each individually an integer of 0 or greater;
    A is -SO 3 X or -COOX, wherein X is H, a metal atom, NR 5 4 , imidazolium optionally containing a substituent, pyridinium optionally containing a substituent, or phosphonium optionally containing a substituent, where R 5 s are each H or an organic group and are the same as or different from each other; and
    L is a single bond, -CO 2 -B-*, -OCO-B-*, -CONR 6 -B-*,-NR 6 CO-B-*, or -CO- other than the carbonyl groups in -CO 2 -B-, -OCO-B-, -CONR 6 -B-, and -NR 6 CO-B-, where B is a single bond or a C1-C10 alkylene group optionally containing a substituent, R 6 is H or a C1-C4 alkyl group optionally containing a substituent, and * indicates the bond to A in the formula.
