    摘要: A method of producing a controlled release form of an agricultural active material includes the provision of an organic liquid composition in which the active is present, but where the liquid composition is free from aromatic solvents and is maintained below the normal melting point of the active. The liquid composition is formed into small droplets and the droplets are enclosed by a non-water soluble shell to provide microcapsules, the shell of which is designed to release the agricultural active at a pre-selected controlled rate when the microcapsule is exposed to natural environmental conditions. Controlled release forms of agricultural actives are also provided.

    摘要: A process for producing melamine-formaldehyde microcapsules using a reactive protective colloid is provided. The reactive protective colloid is prepared by reactively coupling a surface active polymer with a first melamine-formaldehyde pre-condensate. An aqueous solution which includes the reactive protective colloid and a second melamine-formaldehyde pre-condensate is then prepared. A substance to be encapsulated, preferably an oily solution containing a dyestuff precursor, is dispersed as droplets into the aqueous solution. The reactive protective colloid surrounds the droplets to form an emulsion. The second melamine-formaldehyde pre-condensate and the reactive protective colloid are made to self-condense to form melamine-formaldehyde microcapsule walls around the droplets of the substance to be encapsulated.

    摘要: A process for the preparation of a microencapsulated composition comprises: (a) combining (i) a triisocyanate that is an adduct of linear aliphatic isocyanates having the formula O.dbd.C.dbd.N--(CH.sub.2).sub.n --N.dbd.C.dbd.O, where n is from about 4-18, (ii) an aliphatic diisocyanate that contains a cycloaliphatic or aromatic ring moiety, the aliphatic diisocyanate having from about 6-32 carbon atoms, most preferably from about 8-18 carbon atoms, and (iii) a water-immiscible composition comprising a core chemical; (b) adding an aqueous liquid and forming an oil-in-water emulsion; (c) adding a polyamine to the emulsion; and (d) reacting the triisocyanate, the diisocyanate, and the polyamine, thereby producing a plurality of microcapsules having a capsule wall, with at least a major portion of the core chemical encapsulated within the capsule wall of the microcapsules. Suitable core chemicals include agricultural chemicals such as herbicides and safeners. By adjusting the composition of the capsule walls and the contents of the capsule core, the rate of release of the core materials from the microcapsules can be adjusted. When the core contains two or more materials to be released, the microcapsules can provide a more rapid rate of release for one core material than for another.

    摘要: A process for making melamine-formaldehyde microcapsules in an aqueous solution containing a high concentration of a water miscible or water soluble organic solvent is provided. The aqueous solution is prepared and a water insoluble melamine-formaldehyde pre-condensate is dissolved therein by adjusting the temperature and organic solvent concentration of the aqueous solution such that the melamine-formaldehyde pre-condensate is barely soluble therein. A substance to be encapsulated, preferably an oily solution containing a dyestuff precursor, is dispersed into the aqueous solution to form an emulsion, the melamine-formaldehyde pre-condensate being insoluble in the substance to be encapsulated. The melamine-formaldehyde pre-condensate is separated from the aqueous solution onto droplets of the substance to be encapsulated and the self-condensation reaction of the phase-separated melamine-formaldehyde pre-condensate initiated to form capsule walls around the droplets, thereby producing melamine-formaldehyde microcapsules in the aqueous solution containing a high concentration of a water miscible or water soluble organic solvent.
