The use of film-forming, water soluble or water dispersible grafted polymers, which can be obtained by radical polymerization of: (a) vinyl esters of C1-C24 aliphatic carboxylic acids, in the presence of: (b) polyethers with average molecular weight (numerical average) of at least 300, of the formula I ** (See formula) ** in which, the variables, independently of each other, have the following meanings: R1 is hydroxyl, amino, alkoxy of C1-C24, R9-COO-, R9-NH-COO-, polyalcohol residue; R2 to R7 is - (CH2) 2 -, - (CH2) 3 -, - (CH2) 4 -, - CH2-CH (CH3) -, - CH2-CH (CH2-CH3) -, - CH2-CHOR10- CH2-; R8 is hydrogen, C1-C6 amino-alkyl, C1-C24 alkyl, R9-CO-, R9-NH-CO-; R9 is C1-C24 alkyl; R10 is hydrogen, C1-C24 alkyl, R9-CO-; A-CO-O -, - CO-B-CO-O -, - CO-NH-B-NH-CO-O-; B is - (CH2) t-, if desired, substituted arylene; n is 1 or, when R1 means a polyalcohol residue, 1 to 8; s is 0 to 500; t is 1 to 12; u is 1 to 5000 v is 0 to 5000; w is 0 to 5000; x is 1 to 5000; and is 0 to 5000; z is 0 to 5000 as coating materials, matrix formers and / or agrochemical packaging materials. |
