PURPOSE:To prepare the title dispersion which undergoes little viscosity change with time during storage, has a low viscosity even when the solid content is high, and hence is easily processable. CONSTITUTION:The title dispersion is prepd. by dispersing, in a hydrocarbon medium, particles of a modified propylene polymer which is prepd. by reacting a propylene polymer with maleic anhydride to modify the polymer, esterifying a part or the whole of the combined maleic anhydride with an alcohol, etc., and pulverizing the esterified polymer to a mean particle size of 0.1-10mum. |
