Abstract

The invention discloses a hyperdispersant for pesticide. In a general formula, an M part comprises styrene, vinyltoluene, ethyl styrene, methoxy styrene and phenoxy styrene; an N part comprises various kinds of acrylic polyether ester and methacrylic polyether ester; an O part comprises acrylic acid ester containing tertiary amino group; and a P part comprises acyclic acid, methacrylic acid, butenedioic acid and maleic anhydride. The invention also provides a preparation method and application of the hyperdispersant. The hyperdispersant provided by the invention is applied to a pesticide suspension agent (SC) and is low in price, so that the cost of a sub-nano pesticide preparation is low. Therefore, the demand on original pesticide can be greatly reduced, and the pollution to environment and poison brought by production of original pesticide of the pesticide are greatly reduced; and in addition, poisonous residue for soil due to use of pesticide can be greatly reduced, and pesticide residue of crops can be reduced.
