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 drops/particles including target mateial 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 mocroencapsulation of agriculture chemicals and biocides.  
                            一种封装各种目标材料(包括亲
水性和疏
水性材料)的工艺采用了两种反应性化合物的缩合,以在核心相滴/颗粒(包括分散在连续相中的目标材料)周围形成外壳。其中一种反应性化合物每个分子至少有两个活性亚甲基官能团,另一种是活性亚甲基反应性
交联剂。两种活性化合物中的一种可分散在连续相中,另一种可分散在核心相中。其应用包括农用
化学品和杀菌剂的控释微胶囊化。
