Silicone leveling agent had been synthesized using octamethylcyclotetrasiloxane （D4） as reactant, emathlite as catalyst and hexamethyldisiloxane （MM） as end-capping agent. The influences of the mass ratio of D4, MM and emathlite, reaction time and temperature on the levelling property of the asprepared products were investigated. The results showed that, at the condition that the mass ratio of D4, MM and emathlite was 100： 0. 8：1 with the reaction temperature of 70 ℃ and the reaction time of about 3 h, the end-products possessed the optimum leveling property.
