Vinyl-based polymer, method for producing same, polishing liquid, and vinyl-based monomer

Abstract

A vinyl-based polymer contains a structural unit (A) derived from a vinyl-based monomer (A) represented by the following structural formula (1). In the structural formula (1), R represents a hydrogen atom or a methyl group, W represents a divalent hydrocarbon group having 6 or less carbon atoms, X represents a heteroatom-containing divalent functional group having 1 or less carbon atoms, Y represents a divalent hydrocarbon group having 6 or less carbon atoms, Z represents a hydrogen atom or an alkyl group having 1 or more and 4 or less carbon atoms, and n represents an integer of 4 or more. The vinyl-based polymer is obtained, for example, by polymerizing one or more types of vinyl-based monomers including the vinyl-based monomer (A) by a living radical polymerization method.
