Abstract
In recent years a number of papers and patents describing the use of interfacial reactions as a means of microencapsulation have been reported in the literature. This paper discusses the technique of microencapsulation by interfacial reactions and the effect of variables which may influence the integrity of the microcapsules. Variations of the basic interfacial polymerization techniques are described with special reference to interfacial polycondensation, the formation of polymer material by induced catalyzation, vapor deposition technique, and in-situ polymerization. Examples of some processes used and/or the types of reacting species are also included.
