    摘要: A process for encapsulating a wide variety of target materials, including both hydrophilic and hydrophobic materials, employs condensation of two reactive compounds to form shells around core phase particles including target material dispersed in a continuous phase. One of the reactive compounds has at least two active methylene functional groups per molecule, the other being an active methylene-reactive crosslinking agent. Either type of the reactive compounds can be dispersed in the continuous phase, the other being dispersible in the core phase. Applications include controlled release microencapsulation of agriculture chemicals and biocides.
