These two volumes, available separately, inaugurate a new series. IPNs are of considerable interest in both fundamental and applied R&D investigations, and have found commercial application in many areas. The 13 technical reports in Volume 1 discuss the results of R&D in specific IPNs such as polyurethane/epoxide-episulfide resin, latex, polydimethylsiloxane/polydeuterostyrene, polybutadiene-based polyurethane, and others. The reports in Volume 2 (708-8) describe the preparation, characterization, properties, and applications of IPNs, synthesized in the traditional forms of films and sheets, as well as in the form of foams, porous beads, and fibers.
