✦ Synopsis


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 d-temperature curves of the interface region have been extracted and the relative amounts of interface region have been determined.

A predictive scheme is proposed for the simultaneous calculation of the modulus and yield (or tensile) strength of ternary polymer systems. According to the continuity or discontinuity of constituting phases, the scheme combines in two steps the models for binary systems: (i) in the interval of phas
