Use of water-soluble or water-dispersible, film-forming graft polymers which can be obtained by radical polymerization of DOLLAR A (a) vinyl esters of aliphatic C¶1¶-C¶24¶ carboxylic acids in the presence of DOLLAR A (b) polyethers of average molecular weight (number average) of at least 300 of the general formula I DOLLAR F1 in which the variables have the following meaning independently of one another: DOLLAR AR · 1 · hydroxy, amino, C¶1¶-C¶24¶-alkoxy, R · 9 · -COO-, R · 9 · -NH-COO-, polyalcohol residue; DOLLAR AR2 to R7 -CH¶2¶) ¶2¶-, - (CH¶2¶) ¶3¶-, - (CH¶2¶) ¶4¶-, -CH¶2¶ -CH (CH¶3¶) -, -CH¶2¶-CH (CH¶2¶-CH¶3¶) -, -CH¶2¶-CHOR · 10 · -CH¶2¶-; DOLLAR AR · 8 · hydrogen, amino-C¶1¶-C¶6¶-alkyl, C¶1¶-C¶24¶-alkyl, R · 9 · -CO-, R · 9 · -NH-CO- ; DOLLAR A R · 9 · C¶1¶-C¶24¶ alkyl; DOLLAR A R · 10 · hydrogen, C¶1¶-C¶24¶-alkyl, R · 9 · -CO-; DOLLAR A A -CO-O-, -CO-B-CO-O-, -CO-NH-B-NH-CO-O-; DOLLAR A B - (CH¶2¶) ¶t¶-, optionally substituted arylene; DOLLAR A n 1 or, if R · 1 · is a polyalcohol radical, 1 to 8; DOLLAR A s 0 to 500; t 1 to 12; u 1 to 5000; v 0 to 5000; DOLLAR A w 0 to 5000; x 1 to 5000; y 0 to 5000; z 0 to 5000 DOLLAR A as a coating agent, matrix former and / or packaging material for agrochemicals. |
