Zusammenfassung:2083185 9113546 PCTABS00007 Low cost, rapidly water-dispersible or water-soluble granular compositions containing at least 10 % voids and consisting of agglomerates comprised of pesticidal particles bonded together by solid bridges of a water-soluble heat-activated binder, the water-soluble heat activated binder having a melting point range within 40· to 120 ·C, a difference of less than 5 ·C between the softening point and the onset of solidification, a hydrophile/lipophile balance of about 14 to 19, a dissolution time of not greater than about 50 minutes; and a melt viscosity of at least about 200 cps. Examples of suitable heat-activated binders, which are not intended to be limiting, are ethylene oxide/propylene oxide copolymers and polyethoxylated dinonylphenol.
