Resin, method for producing resin, curable resin composition, and cured product

A resin being a reaction product of a resin containing constituent units described in Group (2) and a compound represented by Formula (3),

• where R1 each independently represent a methylene group, a methylene oxy group, a methylene oxy methylene group, or an oxy methylene group, R2 and R3 each independently represent a halogen atom, an alkyl group having from 1 to 10 carbons, a halogenated alkyl group having from 1 to 10 carbons, a hydroxy alkyl group having from 1 to 10 carbons, or an aryl group having from 6 to 12 carbons, x represents 0 or 1, and y and z each independently represent a number of 0 to 3, a, b, and c each independently represent a molar ratio of the constituent units, a represents a number of 1 or greater, b represents a number of 0 or greater, and c represents a number of 1 or greater, R1 may bond each other to form a crosslinking structure, and * represents a bonding position with another constituent unit or a terminal group,
• where R4, R5, and R6 each independently represent a hydrogen atom, a halogen atom, an alkyl group having from 1 to 10 carbons, a halogenated alkyl group having from 1 to 10 carbons, a hydroxy group, a hydroxy alkyl group having from 1 to 10 carbons, or an aryl group having from 6 to 12 carbons, and L represents a halogen atom.

A method for producing a resin, the method comprising reacting a resin containing constituent units described in Group (2) and a compound represented by Formula (3) in the presence of a basic compound,

• where R1 each independently represent a methylene group, a methylene oxy group, a methylene oxy methylene group, or an oxy methylene group, R2 and R3 each independently represent a halogen atom, an alkyl group having from 1 to 10 carbons, a halogenated alkyl group having from 1 to 10 carbons, a hydroxy alkyl group having from 1 to 10 carbons, or an aryl group having from 6 to 12 carbons, x represents 0 or 1, and y and z each independently represent a number of 0 to 3, a, b, and c each independently represent a molar ratio of the constituent units, a represents a number of 1 or greater, b represents a number of 0 or greater, and c represents a number of 1 or greater, R1 may bond each other to form a crosslinking structure, and * represents a bonding position with another constituent unit or a terminal group,
• where R4, R5, and R6 each independently represent a hydrogen atom, a halogen atom, an alkyl group having from 1 to 10 carbons, a halogenated alkyl group having from 1 to 10 carbons, a hydroxy group, a hydroxy alkyl group having from 1 to 10 carbons, or an aryl group having from 6 to 12 carbons, and L represents a halogen atom.
