Poly(methyl methacrylate) (PMMA) is one of the general glassy polymers and has high transparency. In this study, I have focused on the mechanical properties of PMMA doped with some metal salts. The effects of molecular interaction between PMMA molecules and the metal salts were quantitatively evaluated due to the viscoelastic properties of the salt-doped samples. Moreover, a kinetical constitutive equation was proposed for the effects of water absorption on the stress-strain behavior of PMMA doped with a salt at the different salt concentrations.
