Assessing the Range of Validity of Current Tube Models
through Analysis of a Comprehensive Set of Star–Linear 1,4-Polybutadiene
Polymer Blends
Posted on 2019-10-10 - 03:13
We blend newly synthesized nearly
monodisperse four-arm star 1,4-polybutadienes
with various well-entangled linear polymers, confirming the conclusions
in Desai et al. [Macromolecules201649 (13)49644977] that advanced tube models, namely,
the hierarchical 3.0 and branch-on-branch models [Wang, Z.; J. Rheol.201054 (2)223260], fail to predict
the linear rheological data when the pure linear polymers have shorter
relaxation times, but within 3–4 orders of magnitude of the
star polymer. However, when the linear polymer has a longer relaxation
time than the star, our new work, surprisingly, finds that non-monotonic
dependence of terminal relaxation behavior on composition is both
observed experimentally and captured by the models. Combined with
previous data from the literature, we present results from over 50
1,4-polybutadiene star–linear blends, suitable for thorough
testing of rheological models of entangled polymers.
