摘要:
The application describes a process for the producing microcapsules which contain a shell made of polyurea obtained in the presence of polyvinyl alcohol copolymers.
摘要:
The invention relates to microcapsules comprising a capsule shell, and a capsule core, wherein the capsule shell comprises a polyester, and wherein the capsule core comprises a water-solu- ble pesticide, and at least 10 wt% of water based on the total weight of the capsule core; to a process for manufacturing said microcapsules; to a method of application of the microcapsules for controlling undesired insect or mite attack, harmfull fungy, and/or undesired vegetation, and/or for regulating the growth of plants; to plant propagation material comprising the micro- capsules; and to the use of the microcapsules for reducing the volatility, or the leaching behav- ior of the pesticide.
摘要:
The application describes an aqueous dispersion of microcapsules, wherein the shell of the microcapsules comprises at least one polyurea and the core comprises one or more lipophilic components with the proviso that the core does not contain a fragrance, and having a percentage of the shell weight with reference to the total weight of the capsules of 5 to 40% and wherein the microcapsules have a volume average diameter of 15 to 90 μm and the dispersion comprises hydroxyalkylcellulose and the use of such a dispersion.
摘要:
The application describes a process for the preparation of microcapsules, wherein the microcapsules have a volume average diameter d of 15 to 90 μηη and a percentage of the shell weight of 3 to 40%, with reference to the total weight of capsules, wherein the shell of the microcapsules comprises at least one polyurea and the core comprises at least one lipophilic component, comprising the step of adding hydroxyalkylcellulose to a dispersion of polyurea microcapsules, microcapsules and their uses.
