ENCAPSULATION PROCESS USING ISOCYANATE MOIETIES |
摘要 |
The invention provides a method of forming microcapsules or particles of a matrix which comprises dispersing a first liquid in a second, immiscible or partially miscible liquid that forms a continuous phase, one liquid containing reactants bearing (a) isocyanate moieties and (b) anhydride moieties, glycidyl moieties or electrophilic moieties bearing base-susceptible leaving groups and the other liquid containing a reactant that bears reactive groups that will react with the reactants in the said one liquid to form a membrane. The microcapsules or particles can encapsulate material that will undergo slow release. The invention also extends to the formed microcapsules or particles.
