A method for studying dynamic mechanical spectroscopy (DMS) is described. By use of factor analysis, the DMS curves of twelve polyurethane/polystyrene ionomer thermoplastic interpenetrating polymer networks were studied. The isolated tan δ‐temperature curves of the interface region have been extracted and the relative amounts of interface region have been determined. © 1997 John Wiley & Sons, Inc.
