Abstract: An agrochemical composition comprising (i) an agrochemical active ingredient; and (ii) a graft polymer comprising (A) a polymer backbone as a graft base, wherein said polymer backbone is obtainable by polymerization of at least one alkylene oxide selected from the group of C2- to C10-alkylene oxides, preferably C2- to C5-alkylene oxides, such as ethylene oxide, 1,2-propylene oxide, 1,2-butylene oxide, 2,3-butylene oxide, 1,2-pentene oxide or 2,3-pentene oxide; and optionally at least one polyol selected from the group of C2- to C14-polyols or at least one polyamine selected from the group of C2- to C14-polyamines; and (B) polymeric sidechains grafted onto the polymer backbone (A), wherein said polymeric sidechains (B) are obtainable by polymerization of monomers comprising at least one vinyl ester monomer (B1) in the presence of the polymer backbone (A). It was found that the graft polymer of the inventive composition is suitable as a dispersant for pesticides in agrochemical compositions. Moreover, the graft polymer typically exhibits a suitably high degree of biodegradability.

Abstract: Described herein is a polymeric stabilizing agent selected from poly-lysine derivatives obtained by process including heating an aqueous lysine solution to boiling, increasing a temperature of the aqueous lysine solution to a reaction temperature in the range of about 105° C. to about 180° C., and keeping the reaction temperature in the range of about 105° C. to about 180° C. until a melt viscosity of the reaction mixture is in the range of about 350 mPa*s to about 6,500 mPa*s, and (ii) an amine number in the range of about 100 mg KOH/g to about 500 mg KOH/g is achieved. The process also includes adding alkyl-carboxylic acid or alkenyl-carboxylic acid in amounts of 2.5 mol % to 10 mol %, and increasing or keeping the reaction temperature in the range of about 105° C. to about 180° C. until number of free alkyl-carboxylic acid or alkenyl-carboxylic acid is ≤9% by weight.
