摘要 |
A dispersing agent for solid particles in water, which is a tall oil pitch partially esterified with a polyalkylene glycol mainly composed of ethylene oxide units of a molecular weight of above 600 or a monoester or monoether thereof and optionally also aminated having a residual acid value higher than 3, and a process for preparing said dispersing agent which comprises heating the two reactants at 200 DEG -285 DEG C. for so long that the maximum acid value of the reaction mixture at this temperature is reduced at least 2 units.
