1. A method, comprising:
removing a unit of formula (2)from a polymer comprising the unit of formula (2) with an azo compound or a peroxide,
wherein the polymer comprising the unit of formula (2) is obtained by radical-polymerizing a vinyl monomer with a compound of formula (1): wherein, in formulae (1): R1 represents an organic group having a hydrophile-lipophile balance (HLB) determined by Griffin's method of 3 or more, wherein the organic group comprises polyethylene glycol, polypropylene glycol, or a polyethylene glycol/polypropylene glycol block copolymer and optionally comprising a carboxylic acid metal salt or sulfonic acid metal salt, wherein when a plurality of R1 are present, they may be the same or different; Z represents an unsubstituted aromatic hydrocarbon group; p is represented by an integer of 1 or more; and R2 is a p-valent organic group having one or more carbons, and said p-valent organic group may comprise at least one of a nitrogen atom, an oxygen atom, a sulfur atom, a halogen atom, a silicon atom, a phosphorous atom and a metal atom, and may represent a high molecular weight substance, and wherein, in formula (2), Z and R1 are the same as in formula (1). |
