ABSTRACT:
The process for the encapsulation of a liquid hydrophobic substance involves, in a first stage, dispersing an organic phase containing the liquid hydrophobic substance to be encapsulated and at least one polyfunctional hydrophobic monomer having functional groups containing the carbonyl or sulphonyl group, in an aqueous phase containing a polyfunctional amine in which the amine functions have been rendered inactive by salification, and subsequently starting polycondensation by liberating the amine functions through the addition, to the aqueous phase, of an equivalent amount of a base which is stronger than the amine. The process has application to the preparation of compounds which can be used especially in the field of plant health.
