I am working on a polyester which remains in sticky viscous state at room temperature. I want to check its shear modulus, viscosity and porosity. Most of the tensile testing needs mold to be formed which is not possible, also due to sticky nature AFM is also not possible. Which tests will be appropriate for there analysis.
Pl. see whether the following articles gives you some isight into this topic.

For measuring viscoelastic properties kindly cheak our following paperBio-Chemical Composition, Functional and Rheological Properties of Fresh Meat from Fish, Squid and Shrimp: A Comparative Study
March 2017International Journal of Food Properties 20(68)

We may want to consider the Williams-Landel-Ferry (WLF) viscosity equation; cf.:
