Encapsulation process |
| abstract |
A PROCESS IS PROVIDED FOR PREPARATION OF MINUTE CAPSULES WHEREIN PARTICLES OF INTENDED INTERNAL PHASE MATERIAL WHICH HAVE BEEN DISPERSED INDIVIDUALLY IN A LIQUID MANUFACTURING VEHICLE ARE COATED BY A SOLID POLYMERIC FILMFORMING MATERIAL. POLYMERIC MATERIAL IS PRECIPITATED FROM SOLUTION IN THE MANUFACTURING VEHICLE OR FROM SOLUTION IN THE INTENDED INTERNAL PHASE MATERIAL DUE TO A "ZONE OF INSOLUBILITY" ESTABLISHED AT THE INTERFACE BETWEEN THE PARTICLES AND THE MANUFACTURING VEHICLE. THE PARTICLES ARE EITHER LIQUID DROPLETS OR SOLID PARTICLES HAVING AN ASSOCIATED LIQUID THEREWITH. THE NOVEL PROCESS IS UTILIZED TO ENCAPSULATE PARTICLES WHICH ARE, TO SOME DEGREE, MISCIBLE WITH THE MANUFACTURING VEHICLE. |
