Method for microencapsulating water-soluble or water-dispersible or water-sensitive materials in an organic continuous phase

摘要

A method for microencapsulating a water-soluble or water-dispersible or water-sensitive material comprising dispersing the water-soluble or water-dispersible or water-sensitive material in an organic continuous phase and adding a polyfunctional isocyanate, a diol or polyol in the presence of an optional polymerization catalyst to the organic continuous phase is described.
