Polyamide and polyimide sticker adjuvants
A sticker adjuvant that may be used in agrochemical compositions is disclosed. The sticker adjuvant is a polyether amide or a polyether imide formed by the reaction of a polyether polyamine with a polyfunctional monomer. The polyfunctional monomer may be a polyacid, a di-functional acyl halide, an acid anhydride, a poly(acid anhydride) and a mixture thereof.
