Title:
Dispersant, fine particle dispersion using it, and method for producing fine particle dispersion
Document Type and Number:
Japanese Patent JP6322080
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a dispersant capable of producing a fine particle dispersion where the content of a free polymer dispersant is extremely small while maintaining the dispersibility of an inorganic fine particle.SOLUTION: A dispersant for dispersing an inorganic fine particle includes a polymer derivative having a polymer unit constituted with a lipophilic polymer (1) expressed by general formula (1), a hydrophilic unit constituted with a hydrophilic group (2) expressed by general formula (2) and a triazole group connecting the polymer unit and the hydrophilic unit. [In the general formula (1),: Rand Rare mutually independent and hydrogen atoms or 1-5C alkyl groups; and m represents an integer of 10-500.] [In the general formula (2), n are mutually independent and represent an integer of 1-5.]SELECTED DRAWING: None
