Abstract:

The purpoe of this program is to develop ultrasoft composite materials to be used as fillers in the fabrication of maxillofacial prostheses. The projected composite systems are elastomeric-shelled, liquid-filled microcapsules. Two experimental approaches were pursued toward making such microcapsules. One approach involves coaxial extrusion of a catalyzed elastomer precursor and core liquid into a receiving bath. The other approach involves interfacial polymerization e.g., of polyurethane around droplets of core liquid suspended in a continuum containing reactive materials e.g., diisocyanates.
