摘要 |
A polymeric dispersant having a hyperbranched polyurethane architecture obtained by reacting a polyisocyanate core with a mixture of: a) 40 to 65 mol % of an anchor represented by Formula (I) and/or (II): wherein n represents an integer selected from 0 to 7; and X and Y each independently represent a primary amine group or a hydroxyl group; b) 5 to 25 mol % of a polypropylene oxide crosslinker; c) 15 to 40 mol % of a polypropylene oxide graft; and wherein the amount of the crosslinker and the graft taken together is at least 35 mol %; and wherein 100 mol % of the mixture corresponds with the total amount of isocyanate groups in the polyisocyanate core.
