| titleOfInvention | A PROCEDURE FOR THE PREPARATION OF SUBSTANTIALLY SOLVENT-FREE MICROCAPSULES. |
| abstract | 1. A process for the preparation of substantially solvent-free microcapsules consisting essentially of a core of an insecticide selected from the group consisting of methomyl, oxamyl, and mixtures of methomyl and an insecticide selected from the group consisting of oxamyl, aldicarb, diflubenzuron, chlordimeform, methyl-parathion, ethyl-parathion, EPN, fenvalerate, permethrin, decamethrin, cypermethrin, carbaryl and leptophos, within an encapsulating wall of cross-linked polyurea, the insecticide constituting at least 10 to 75% of the weight of the microcapsules, which process comprises: (a) dissolving methomyl, oxamyl, or a mixture of methomyl and an insecticide selected from the group consisting of oxamyl, aldicarb, diflubenzuron, chlordimeform, methylparathion, ethyl-parathion, EPN, fenvalerate, permethrin, decamethrin, cypermethrin, carbaryl, and leptophos in methylene chloride containing a polyisocyanate or a mixture of a polyisocyanate and diisocyanate to; (b) emulsifying the solution in a cold aqueous solution of a surface active agent; (c) reacting the emulsion from the previous step with a diamine, a polyamine, or a mixture of both to produce a crosslinked polyurea that forms an encapsulating shell around the droplets of the emulsified solution; and (d) removing the methylene chloride . |
