Abstract:
A compound represented by the following formula (1): wherein R 1  is a 2n-valent group having 1 to 60 carbon atoms; R 2  to R 5  are each independently a linear, branched, or cyclic alkyl group having 1 to 30 carbon atoms, an aryl group having 6 to 30 carbon atoms, an alkenyl group having 2 to 30 carbon atoms, an alkoxy group having 1 to 30 carbon atoms and optionally having a substituent, a halogen atom, a nitro group, an amino group, a carboxylic acid group, a group in which a hydrogen atom of a hydroxy group is replaced with a vinylphenylmethyl group, a group selected from the group consisting of groups represented by the following formula (A), a thiol group, or a hydroxy group, wherein at least one of the R 2  to the R 5  is a group selected from a group represented by the formula (A); m 2  and m 3  are each independently an integer of 0 to 8; m 4  and m 5  are each independently an integer of 0 to 9, provided that m 2 , m 3 , m 4 , and m 5  are not 0 at the same time; n is an integer of 1 to 4; and p 2  to p 5  are each independently an integer of 0 to 2:

Claim (Index 28):
A purification method comprising:\n a step of obtaining a solution (S) by dissolving one or more selected from the group consisting of the compound according to  claim 1  and a resin comprising a constituent unit derived from the compound in a solvent; and a step of extracting impurities in the compound and/or the resin by bringing the obtained solution (S) into contact with an acidic aqueous solution (a first extraction step), wherein the solvent used in the step of obtaining the solution (S) comprises a solvent that does not mix with water.
