[0068] A$_{1}$ , R$_{1}$ , R$_{2}$ , R$_{3}$ , B, and Ar$_{1 }$ in the above reaction scheme have the same definitions as A$_{1}$ , Ri, R$_{2}$ , R$_{3}$ , B, and Ar$_{1 }$ in General Formula (II). 

[0069] Further, Ri’ in the above reaction scheme repre› sents a group formed by removing a hydrogen atom from the hydrocarbon group represented by R$_{1 }$ in General Formula (II). 

[0070] The above reaction proceeds easily in a known condition, but the reaction is preferably carried out by reacting a phenol compound and an olefin compound at a reaction temperature of -30° C. to 50° C., in the absence of a solvent or in the presence of a solvent such as toluene or hexane and in the presence of an acid catalyst. Examples of the acid catalyst to be used include inorganic acids such as hydrochloric acid, sulfuric acid, nitric acid, and perchloric acid; organic acids such as methanesulfonic acid, trifluo› romethanesulfonic acid, p-toluenesulfonic acid, and benze› nesulfonic acid; Lewis acids such as boron trifluoride; and solid acids such as montmorillonite and amberlite. 

[0071] The content of the repeating unit having a structure in which a hydrogen atom of a phenolic hydroxyl group is substituted by a group represented by General Formula (I), or the repeating unit represented by General Formula (II) or (II’) in the polymer compound (A) is preferably in the range of 1 mo! % to 60 mo! %, and more preferably in the range of 3 mo! % to 40 mo! %, based on the total repeating units of the polymer compound (A). 

[0072] The polymer compound (A) preferably further includes a repeating unit represented by the following Gen› eral Formula (III). 

[0073] In General Formula (III), R$_{4 }$ represents a hydrogen atom, a methyl group which may have a substituent, or a halogen atom. B$_{2 }$ represents a single bond or a divalent organic group. Ar$_{2 }$ represents an arylene group, m represents an integer of I or more. 

[0074] In General Formula (III), examples of the substitu› ent which may be substituted on a methyl group represented by R$_{4 }$ include the same substituents as in specific examples and preferred ranges of the substituent which may be substituted on R$_{1 }$ in General Formula (I). R$_{4 }$ in General Formula (II) is preferably a hydrogen atom or a methyl group, and more preferably a hydrogen atom. 

[0075] In General Formula (III), an arylene group repre› sented by Ar$_{2 }$ is preferably an arylene group having 6 to 18 carbon atoms, more preferably a phenylene group or a naphthylene group, and most preferably a phenylene group. 

[0076] Further, the arylene group represented by Ar$_{2 }$ may have a substituent in addition to the group represented by -(OH)m, and examples of the substituent include the same substituents as in specific examples and preferred ranges of the substituent which may be substituted on R$_{1 }$ in General Formula (I). 

[0077] m in General Formula (III) is an integer of 1 or more, preferably an integer in the range of 1 to 5, and more preferably 1. 

[0078] Further, in General Formula (I), when Ar$_{2 }$ is a phenylene group and mis 1, the bonding position of -OH with respect to the benzene ring of Ar$_{2 }$ may be a para› position, a meta-position, or an ortho-position with respect to the bonding position of B$_{2 }$ with respect to the benzene ring of Ar$_{2}$ , but is preferably a para-position or a meta› position. 

[0079] In General Formula (III), examples of the divalent organic group represented by B$_{2 }$ are the same as in specific examples and preferred ranges of the divalent organic group represented by B in General Formula (II). 

[0080] The repeating unit represented by General Formula (III) is preferably a repeating unit represented by the fol› lowing General Formula (III’). 

[0081] In General Formula (III’), R$_{4 }$ represents a hydrogen atom, a methyl group which may have a substituent, or a halogen atom. Ar$_{2 }$ represents an arylene group. m represents an integer of 1 or more.
