摘要： A dispersant of general Formula I T—(A)n(B)p—Z (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 δ-valerolactone, ε-caprolactone or alkyl substituted ε-caprolactone provided that both are not ε-caprolactone or δ-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, δ-caprolactone, 7-methyl-ε-caprolactone with PEI, the reaction product of lauric acid, ε-caprolactone, δ-valerolactone with PEI and the phosphate of the reaction product of dodecanol, ε-caprolactone and δ-valerolactone.

摘要： Basic and acid dispersants derived from branched alkyl aliphatic acids and alcohols and one or more hydroxy carboxylic acid or lactone to give a polyoxyalkylenecarbonyl chain (POAC) having a terminal carboxylic acid group (TPOAC acid) or terminal hydroxy group (TPOAC alcohol). Preferred basic dispersants are obtained by reaching one or more TPOAC acids with a polyamine or polyimine such as polyethyleneimine and preferred anionic dispersants are prepared by forming a phosphate ester of a TPOAC alcohol.
