Abstract
The viscoelastic properties of M(2)(octanoate)(4) compounds, where M = Mo and Cu, are reported in their mesophase as a function of temperatu re dependence, strain sweep (1 rad/s), and frequency sweep (2% strain) . The viscoelastic properties of the mesophase are comparable to that of polypropylene having M(w) exceeding 10(5) kg/kmol. The nonlinear re sponse of G', G '', and eta with increasing strain and the greater va lues of these parameters for M = Cu relative to M = Mo are correlated with the dynamics of the microstructure of the mesophase.
