摘要:
A process for preparing microcapsules which comprises dispersing a hydrophobic oily liquid in a continuous aqueous phase, the hydrophobic oily liquid containing a pre-wall former and at least one chain extender, the chain extender being a polyhydric compound which is capable of reacting with the pre-wall former at a rate such that the chain extender does not substantially react with the pre-wall former prior to dispersing the hydrophobic oily liquid in the continuous aqueous phase; and forming capsule walls around the droplets of hydrophobic oily liquid in the continuous aqueous phase.
摘要:
The present invention is directed to a method for preparing microcapsules which comprises:preparing an aqueous dispersion or emulsion of a hydrophobic oily core material containing a polyvalent isocyanate, a polyvalent isothiocyanate, or an adduct thereof, having an anionic moiety; andforming capsule walls around the droplets of said oily core material.
