Method for microcapsulizing plant pathology product by interfacial copolymerization and product obtained thereby

Abstract

Abstract PURPOSE: To obtain microcapsules gradually diffused with active components by the interfacial polymn. between an org. phase contg. a water insoluble active component and polyfunctional monomer (a) which do not react with each other and an aq. phase contg. a polyfunctional monomer (b) and a catalyst. CONSTITUTION: The sheaths of the microcapsules are formed by the interfacial polymn. between an org. phase A contg. the >=1 water insoluble active component (particularly the products of a plant pathological region, the products of a human or animal pharmaceutical region or the products obtainable by a microbiological or chemical method like virus and enzyme) and the polyfunctional monomer (a) (preferably the diester of phthalic acid) and the aq. phase B contg. the polyfunctional monomer b (preferably an aminoplastic resin) and the catalyst. The execution of the microcapsulation is by a method of dispersing the org. phase into the aq. phase or emulsifying the org. phase into the aq. phase and adding the polyfunctional monomer (b) thereto. The gradual diffusion of the active components by the structure and porosity of the membranes is made possible by the method.
