Abstract
A method for preparing a polymer compound including copolymerizing a monomer (m0-1) and a monomer (m0-2) to obtain a first polymer compound and causing the first polymer compound and an acid component to react with each other to obtain a second polymer compound. In the formulae, Rand Rare each a hydrogen atom, an alkyl group having 1 to 5 carbon atoms and a halogenated alkyl group having 1 to 5 carbon atoms, Vais a divalent hydrocarbon group which may have an ether bond, nis an integer of 0 to 2, Rais a tertiary alkyl ester-type acid dissociable group, Vais a divalent linking group containing a heteroatom, or a single bond, Rais a monovalent organic group, nis an integer of 0 to 3, Rais an acid dissociable group, and nis an integer of 1 to 3.
