| 摘要 |
The invention relates to water-soluble or water-dispersible, film-forming graft polymers which are obtained by radical polymerization of (a) the vinyl esters of aliphatic C1-C24 carboxylic acids in the presence of (b) the polyethers having an average molecular weight (number average) of at least 3 00 of the general formula (I), wherein the variables independently have the following meanings: R1 represents hydroxy, amino, C1-C24 alkoxy, R9-COO-, R9 - NH-COO-, a polyalcohol group; R2 to R7 represent -(CH2)2-, -(CH2)3-, -(CH-2) 4- , -CH2-CH(CH3)-, -CH2-CH(CH2-CH3)-, -CH2-CHOR10-CH2-; R8 represents hydrogen , amino-C1-C6 alkyl, C1-C24 alkyl, R9-CO-, R9-NH-CO-; R9 represents C1-C24 alkyl; R10 represents hydrogen, C1-C24 alkyl, R9-CO-; A represents -CO-O-, - CO- B-CO-O, -CO-NH-B-NH-CO-O-; B represents -(CH2)t- or optionally a substituted arylene; n is 1 or, if R1 is a polyalcohol group, n is 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 ; y is 0 to 5000; and z is 0 to 5000. The inventive polymers can be used as coating agents, matrix formers and/or packaging materials for agrochemicals. |
