Aqueous compositions containing inorganic particles

Abstract

This invention provides a composition (slurry) containing inorganic particles and water, which inhibits the precipitation of inorganic particles. The composition of this invention contains inorganic particles, a copolymer (P) obtained by living polymerization, and water, characterized in that: the copolymer (P) contains structural units (a-1) with side chains having the structure represented by formula (1), and structural units (b-1) with side chains having an azole structure. *-R13-(OR12)m1-OR11 (1) In formula (1), R11 represents a hydrogen atom or an alkyl group having 1 to 3 carbon atoms. R12 represents an alkyl group having 1 to 3 carbon atoms. R13 represents an alkyl group having 1 to 3 carbon atoms. m1 represents an integer from 0 to 30. Furthermore, when m1 is 2 or more, there may be multiple R12s that are the same or different. * indicates a bond.
