Abstract:

The applicability of experimental viscoelastic techniques involving sinusoidal mechanical shear is examined for several types of rheological systems. Data are first presented for NBS polyisobutylene to establish validity for the approach used. General categories that are investigated include elastomers, filled systems, pure liquids, slurries, or suspensions, solutions and gels, foodstuffs, and polymer melts. A modification of the familiar time-temperature superposition routine is proposed by which both entropy and energy relaxation processes can be treated for liquids and polymers alike. Author
