Dynamic mechanical behavior of filled polyethylenes and model composites

Abstract

Abstract The effect of CaCO 3 filler presence and CaCO 3 ‐polymer interface character on the dynamic mechanical spectra of three polyethylenes with different molecular weights was investigated. Differences in storage modulus and loss tangent were observed for different polymer‐filler coupling and polyethylene molecular weight. The dynamic behavior of model composites was estimated using the, etastic‐viscoelastic correspondence principle, and these predictions were compared to the behavior of real materials.
