PERMEABILITY OF ENVELOPES OF MICROCAPSULES BASED ON UNMODIFIED GELATIN

The influence of the polymer ratio and solution acidity an coacervate properties in the gelatin-carboxymethyl cellulose system has been stud ied. The data obtained were used to determine the most favorable condi tions for microencapsulation. Kinetics of nonanol release from the cor e of microcapsules into the medium (hexane, water) have been studied a t 25 degrees C by the method of a rotating bowl with GLC monitoring Th e treatment of microcapsules with Styromal solution (0.5% relative to gelatin weight) results in the formation of a water-resistant envelope . The substance can be transported through this envelope by diffusion.
