| 发明名称 | Microcapsules comprising anionic pesticides | ||
| 摘要 | Microcapsules comprising a core (a) and a shell (b), wherein the core comprises a salt of an anionic pesticide (a1) and optionally a water immiscible solvent (a2), wherein the cation of the salt of the anionic pesticide is an ammonium, phosphonium or sulfonium cation, wherein the groups on the ammonium, phosphonium or sulfonium cation, taken together contain at least 12 and no more than 50 cation atoms and wherein the ratio of the number of carbon atoms in the group with the largest number of carbon atoms to the average number of carbon atoms of all groups on the N, P or S-atom is less than 3.0. | ||

| 主权项 | 1. Microcapsules comprising a core (a) and a shell (b), wherein the core comprises a salt of an anionic pesticide (a1) in dissolved form and a water immiscible solvent (a2) having a solubility in water of up to 20 g/l at 20° C., wherein the cation of the salt of the anionic pesticide is an ammonium, phosphonium or sulfonium cation, wherein the groups on the ammonium, phosphonium or sulfonium cation, taken together contain at least 12 and no more than 50 carbon atoms and wherein the ratio of the number of carbon atoms in the group with the largest number of carbon atoms to the average number of carbon atoms of all groups on the N, P or S-atom is less than 3.0, wherein the shell (b) is a polyurea shell. | ||
