FP-0103 TITLE BLOCK COPOLYMER DISPERSANTS Block copolymers composed of similar monomers but which exhibit substantially different polarity provide excellent performance as pigment dispersants. One of the blocks has cationic ammonium, phosphonium or sulfonium moieties. Each of the blocks is formed from monomers of the formulas CH2=CHCO2R and CH2=CCH3CO2R, where R is alkyl or alkyl ether, with one of the blocks containing at least two pendant ionic moieties. The block copolymers may be prepared using group transfer polymerization techniques. |
