Composition suitable for use as a pigment dispersant, pigment dispersion in an organic solvent and coating composition

摘要

"COMPOSITION SUITABLE FOR USE AS A PIGMENT DISPERSANT, PIGMENT DISPERSION IN AN ORGANIC SOLVENT AND COATING COMPOSITION". The present invention deals with acrylic AB block copolymers prepared through group transfer polymerization which are useful as pigment dispersants, characterized by mononuclear or binuclear heterocyclic groups linked to the highly polar anchoring segment A of the main block copolymer to facilitate attachment to a pigment surface and to improve dispersant efficiency in paint systems containing solvents.
