<p>A dispersant of general Formula (1)
wherein T is hydrogen or a polymerisation terminating group; Z is an acidic or basic group or a moiety containing either an acidic or basic group; A and B are each, independently, oxyalkylene carbonyl groups derivable from ´-valerolactone, µ-caprolactone or alkyl substituted µ-caprolactone provided that both are not µ-caprolactone or ´-valerolactone, n and p are integers; and n + p is from 2 to 100; including salts thereof. Specific examples of dispersants are the reaction product of lauric acid, µ-caprolactone, 7-methyl-µ-caprolactone with poly(ethyleneimine), the reaction product of lauric acid, µ-caprolactone, ´-valerolactone with poly(ethyleneimine) and the phosphate of the reaction product of dodecanol, µ-caprolactone and ´-valerolactone.</p> |
