Claim 24:
25. A method for producing a compound represented by Formula (1), the method comprising:
a step of reacting a polyfunctional thiol compound with a macromonomer which has at least one repeating unit selected from a polyether repeating unit, a polyester repeating unit, a polyamide repeating unit, a polyimide repeating unit, a polyimine repeating unit, or a polyurethane repeating unit, and of which a weight-average molecular weight is 1000 or more; and
a step of polymerizing a monomer having an ethylenically unsaturated bonding group in the presence of a reaction product obtained in the step of reacting,, in Formula (1), R1 represents an (m+n)-valent linking group,
P1 represents a polymer chain which is represented by Formula (P1-1) and of which a weight-average molecular weight is 1000 or more,, in Formula (P1-1), A1 represents a single bond or a divalent linking group, L1 represents a polyether repeating unit, a polyester repeating unit, a polyamide repeating unit, a polyimide repeating unit, a polyimine repeating unit, or a polyurethane repeating unit, x represents a number of 2 or more, W1 represents a hydrogen atom, or a substituent selected from the group consisting of an alkyl group, an aryl group, a heteroaryl group, an alkoxy group, an aryloxy group, a heteroaryloxy group, an alkylthioether group, an arylthioether group, a heteroarylthioether group, the substituent being unsubstituted or substituted with an additional substituent selected from the group consisting of an alkyl group, an aryl group, a heteroaryl group, an alkoxy group, an aryloxy group, a heteroaryloxy group, an alkythioether group, an arylthioether group, and a heteroarylthioether group, and a wavy line represents a linking hand,
P2 represents a polymer chain which is different from P1 and has a repeating unit derived from a monomer having an ethylenically unsaturated bonding group in a main chain,
m represents a number of 1 to 9, n represents a number of 1 to 9, and m+n satisfies 4 to 18,
in a case where m is 2 or more, m P1′s may be the same as or different from each other, and
in a case where n is 2 or more, n P2′s may be the same as or different from each other.
