TL;DR: In this article, a simple lattice-based equation of state was applied to search for patterns in a large sample of experimental blend, which revealed new correlations revealed by their study of polymer mixture miscibility.

TL;DR: The results revealed that the PU/BS films possessed much higher optical transmittance and tensile strength than the pure PU film, and the interaction between the PU and the BS with relatively low M(w) was stronger than that with high M( w).

TL;DR: The composition dependence of the multiple glass transitions detected in these weakly segregated copolymers are predicted by the self-concentration model for a miscible blend made of components with a large Tg contrast.
Abstract: Thermally stimulated depolarization currents, TSDC, wide-angle X-ray scattering, WAXS, differential scanning calorimetry, DSC, and polarized light optical microscopy, PLOM, have been used to examine poly(L-lactide)-b -poly( $ \upvarepsilon$
-caprolactone) diblock copolymers in a wide composition range. Both components are crystallizable and the miscibility in the amorphous phase has been determined from the behavior of the primary relaxations which are the dielectric manifestation of the glass transition, and also from the superstructural morphology revealed by PLOM and the compositional dependence of the melting points as determined by DSC. Distinct segmental mobilities in the amorphous phase which can be well resolved by TSDC are present; the $ \upalpha$
mode of the slower component shifts to lower temperatures as the PCL content increases while the glass transition of neat PCL is present for all compositions. A relaxation times bimodal distribution is apparent for PCL-rich copolymers. The composition dependence of the multiple glass transitions detected in these weakly segregated copolymers are predicted by the self-concentration model for a miscible blend made of components with a large Tg contrast.
