The use of a water soluble water dispersible film forming graft polymerisate comprises: (a) vinyl esters of 1-24C carboxylic acids, in the presence of (b) polyethers of mean number average molecular wt. 300 (I), as coating agents, matrix builders,and/or packaging materials for agrochemicals. The use of a water soluble water dispersible film forming graft polymerisate comprises: (a) vinyl esters of 1-24C carboxylic acids, in the presence of (b) polyethers of mean number average molecular wt. 300 of formula (I), as coating agents, matrix builders,and/or packaging materials for agrochemicals. R<1> = OH, amino, 1-24C alkoxy, R<9>-COO, R<9>-NH-COO-, polyalkoxy; R<2>-R<7> = (CH2)2, (CH2)3, (CH2)4, CH2CH(CH3), CH-2-CH(CH2-CH3), CH2-CHOR<10>-CH2 R<8> = H, amino-1-6 alkyl , 1-24 alkyl, R<9>-CO, R<0>-NH-CO; R<9> = 1-24C alkyl; R<10> = H, 1-24C alkyl, R<9>-CO; A = COO, CO-B-COO, CONH-B-NH-COO; B = (CH2)t or optionally substituted arylene; n = 1; s = 0-500; t = 1-12; u = 1-5000; v = 0-5000; w = 0-5000; x = 1-5000; y = 0-5000; z = 0-5000; and provided that when R<1> is polyalcohol, n is 1-8. An Independent claim is also included for agrochemical preparations in tablet form, containing a coating formulation of one or more agrochemical active agents as tab let cores with one or more graft polymerisates. |
