ABSTRACT:
Dispersions useful in making capacitors, printed circuit boards, etc., comprising an electronic particulate solid, a carrier and a dispersant of formula (1): R—(O-A-CO)x(O—B—CO)y-Z wherein R is hydrogen or a polymerisation terminating group; A is C8-20-alkylene and/or C8-20-alkenylene; B is C1-6-alkylene or a lactone thereof; Z is hydroxyl or a basic group or a moiety containing a basic group; x is from 2 to 45; Y is from 0 to 15; and the ration of x:y is not less than 3:1, the carrier is a high boiling organic liquid having a boiling point between 150 and 350° C. selected from monohydric alcohols and esters of dialkylene glycol monoalkyl esters.
