摘要:
A dispersion comprising (a) a continuous liquid phase and (b) a solid phase of epoxy-polymer particles dispersed in the continuous liquid phase where the polymer is formed from monomers that are insoluble in the continuous phase a chemical agent is present within the polymer particles and the dispersion is not a Pickering dispersion and optionally the polymer molecules that form the polymer particles contain hydrophilic groups that hydrate on exposure to water in a manner that renders the particles permeable and that allows the chemical agent to diffuse out, and optionally at least one non-cross-linkable mobile chemical such that the extraction of this chemical from the dispersed phase renders it porous in a manner that allows the chemical agent to diffuse out. In one aspect, the chemical agent is a solid and is distributed within the dispersed solid phase or is a liquid and is distributed within the dispersed solid phase. When the chemical agent is an agricultural active ingredient, the compositions of the invention can be used directly or with dilution to combat pests or as plant growth regulators.
