| Abstract: | Highlights: [•] The study explores correlation between chemistry and rheology of aged PMA. [•] Severity of aging procedure, polymer content and its concentration affect PMA viscosity. [•] Complex shear modulus can be fairly estimated from chemical composition elucidated by ATR FT-IR. [•] Polymer concentration can be backcalculated from absorbance spectrum of PMA.
