Coupling Kinetic Modelling with SAOS and LAOS Rheology of Poly (n ‐Butyl Acrylate)

Abstract: A kinetic model based on fundamentals of radical polymerization and literature known rate parameters for the polymerization of n‐butyl acrylate is validated against molecular analysis and rheological data. The model is used to predict conversion, molar mass distribution, and branching densities in form of short and long chain branching. Rheological measurements of synthesized model polymers are evaluated along the Carreau‐Yasuda and Van Gurp‐Palmen presentations, allowing to detect small differences in the degree of long chain branching. Contributions of anharmonics to viscoelastic response in large amplitude oscillations are small and differences between the products are dominated by the differences in molar mass.
