FTIR and FT-Raman Studies of Partially Miscible Poly(methyl methacrylate)/Poly(4-vinylphenol) Blends in Solid States
Jian Dong,Yukihiro Ozaki +1 more
TL;DR: In this paper, the miscibility of poly(4-vinylphenol) (PVPh) and poly(methyl methacrylate) (PMMA) blends has been investigated by FTIR and FT-Raman spectroscopy.

In Situ Spectroscopy of Polymers Subjected to Supercritical CO2: Plasticization and Dye Impregnation
TL;DR: In situ FT-IR spectroscopy has been used to study poly(methyl methacrylate) films subjected to high-pressure and supercritical CO2 as discussed by the authors, which indicate increased molecular mobility of ester groups due to the plasticization effect of CO2 on PMMA.
Journal ArticleDOI
Molecular-weight dependence of the glass transition temperature of freely-standing poly(methyl methacrylate) films.
TL;DR: The observed differences between the freely-standing PMMA and PS film data suggest that differences in chemical structure determine the magnitude of the Tg reduction and the possible origins of these differences are discussed.
Journal ArticleDOI
Energetic analysis of the two PMMA chain tacticities and PMA through molecular dynamics simulations
TL;DR: In this article, the difference in T g s between the two configurations was accurately simulated, and further analysis could be carried out, more particularly dealing with energetic and structural analysis of the difference, which showed that the non-bond energy and the bending angle energy associated with the intradiad backbone angle, principally contribute to the energetic difference between two PMMA configurations.

Glass Transition Temperature Determination of Poly(ethylene terephthalate) Thin Films Using Reflection−Absorption FTIR
TL;DR: In this article, the glass transition temperatures of poly(ethylene terephthalate) thin films were determined by detecting the abrupt change in the absorbance ratio of two comparable bands at 1340 cm-1 (trans conformation) and 1370 cm -1 (gauche conformation).
