Dispersants |
abstract |
A dispersant of formula (1): R-[-(O-A-CO-)-n(Gly-m]-z, wherein R is hydrogen or a polymerisation termination group; Z is an acidic or basic group or a moiety containing either an acidic or basic group; A is C3-7alkylene optionally substituted by alkyl; Gly is oxymethylenecarbonyl; n and m are integers; and n + m is from 2 to 100. The dispersants are used to disperse particulate solids such as pigments in paints and inks. Examples of the dispersants include mixed polyester chains derived from ⊂-caprolactone and/or δ-valerolactone with glycolic acid where the mixed polyester chain is reacted with either a polyalkyleneimine or with a phosphating agent. |
