Abstract The dynamic viscoelastic properties of liquid crystalline polymer (LCP) and polyethylene terephthalate (PET) blends were studied at two different temperatures: 265°C at which LCP was in solid state and 285°C at which LCP was in molten state. The PET was in molten state at both the temperatures. The storage modulus, G’, loss modulus, G’’, dynamic viscosity, h’, of blends with different compositions were evaluated and compared. The morphology of these samples was studied using scanning electron microscope, which exhibited composition dependency. A maxima was observed in the viscosity versus composition plot corresponding to 90/10 LCP/PET blend at 285°C. The G’ versus G’’ plots demonstrated the composition dependency of LCP/PET blends.

Abstract A systematic characterization of gum elastomers may be done by measuring viscoelastic and ultimate properties. The viscoelastic properties of amorphous elastomers can be reduced to a master curve by means of the temperature-time, pressure-time, and strain-time correspondence principles. If a structure, e.g. crystallinity, develops with a change of temperature, pressure, or strain, such structural change may be regarded as a deviation. The ultimate properties may be represented either as stress-strain at break, modulus-strain at break, rupture-energy-deformation-rate, or stress-at-break-deformation-rate and strain-at-break-deformation-rate. The modulus-strain-at-break plot shows promise for interpreting mill processability in terms of the basic rheological properties. The rupture-energy-deformation-rate plot supplies a useful quantitative input for mill mixing.
