Abstract

1. Технический результат Increase in concentration of microcapsules in an aqueous slurry at simultaneous increase of the contents of pesticide in a capsule. 2.Essence Reception of an aqueous dispersion of microcapsules with encapsulated wall from polyurea and a nucleus from a pesticide not mixing up with water by dispersion in water of a solution of polyisocyanate in pesticide, introduction of water solution of polyamine and stirring in the presence of the anionic disperser selected from the group including salt of condensation product of naphthalene monosulphonic acid with phenol-sulphonic acid and formaldehyde, salt polystirol sulphonic acid and salt of a nonionic protective colloid mol.m.10000-20000. 3. Field of Application Organic chemistry.
