    Abstract: A method for removing residual styrene monomers from co-extrudates comprising polystyrene and water-insoluble, crosslinked polyvinylpyrrolidone, which comprises subjecting an aqueous suspension of the particulate solid co-extrudate to a heat treatment at temperatures of 60 to 99° C., the weight ratio of solid co-extrudate to water in the suspension being 1:1.5 to 1:20, and the concentration of the suspension being kept constant during the treatment.

    Abstract: 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 = OH, amino, 1-24C alkoxy, R -COO, R -NH-COO-, polyalkoxy; R -R = (CH2)2, (CH2)3, (CH2)4, CH2CH(CH3), CH-2-CH(CH2-CH3), CH2-CHOR -CH2 R = H, amino-1-6 alkyl , 1-24 alkyl, R -CO, R -NH-CO; R = 1-24C alkyl; R = H, 1-24C alkyl, R -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 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.
