Phase Behavior of Pyrene and Vinyl Polymers with Aromatic
Side Groups
Posted on 2017-10-17 - 11:20
The
phase behavior and thermodynamic properties of mixtures of
pyrene and model vinyl polymers with and without aromatic side groups
are investigated using differential scanning calorimetry (DSC) measurements.
The melting temperature and associated heat of melting of the pyrene
crystals in the mixtures are utilized to extract the effective interaction
parameters χ and the composition of polymer-rich phases, respectively.
The χ of pyrene mixed with polymers with aromatic side groups
investigated in this study, polystyrene, poly(2-vinylpyridine), and
poly(3-vinylanisole), is less than 0.5 at the melting point of the
pyrene crystals, suggesting that pyrene and the polymers with aromatic
sides groups are enthalpically compatible, likely due to aromatic
π–π interactions. In contrast, the χ of pyrene
mixed with poly(1,4-isoprene) or poly(ethylene-alt-propylene) is larger than 0.5. The DSC measurements also enable
characterization of the composition of polymer-rich phases. Interestingly,
the polymers with aromatic side groups are found to have more pronounced
miscibility with pyrene at symmetric compositions.
