- Solution behavior of polyimide-graft-polystyrene copolymers in selective solvents
Alexander P. Filippov, Elena V. Belyaeva, Tamara K. Meleshko and Alexander V. Yakimansky
Article first published online: 19 SEP 2014 | DOI: 10.1002/polb.23595
The conformation and hydrodynamic properties of graft-copolymers with a polycondensation-type backbone and polymerization-type side chains are caused by the difference in the solvent thermodynamic quality with respect to these components. In good solvents, the conformation of the studied graft-copolymer is a wormlike spherocylinder (as usual polymer brushes) but the backbone is somewhat folded. In Θ-conditions, macromolecules of the investigated polymer form a dense core–shell structure due to the backbone collapse.

A new trend of harnessing buckling mechanics of polymer films for beneficial functions has emerged in recent years. This review describes the basic governing principles of several different types of elastic buckling instabilities—including wrinkling, creasing, global buckling, folding, and snapping—and highlights potential applications and recent advances in controlling these processes using a variety of triggering stimuli.
- Characterization of free, restricted, and entrapped water environments in poly(N-isopropyl acrylamide) hydrogels via 1H HRMAS PFG NMR spectroscopy

Article first published online: 18 SEP 2014 | DOI: 10.1002/polb.23591
Free, restricted, and entrapped water environments in poly(N-isopropyl acrylamide) (PNIPAAm) hydrogels are characterized using high resolution magic angle spinning (HRMAS) NMR techniques. Changes in behavior of these water species are investigated at temperatures below and above the lower critical solution temperature (LCST). By coupling HRMAS NMR with pulse field gradient (PFG) diffusion measurements it is possible to directly measure the transport properties of these different water environments in the PNIPAAm hydrogels.
- Enthalpy of fusion of poly(3-hexylthiophene) by differential scanning calorimetry
Roddel Remy, Emily Daniels Weiss, Ngoc A. Nguyen, Sujun Wei, Luis M. Campos, Tomasz Kowalewski and Michael E. Mackay
Article first published online: 12 SEP 2014 | DOI: 10.1002/polb.23584
Knowledge of the enthalpy of fusion for poly(3-hexylthiophene) is important to determine its crystallinity after it is deposited or processed. Differential scanning calorimetry (DSC) of low molecular weight samples is demonstrated to be an effective technique to obtain it. Grazing incidence small angle scattering was employed to find a correction factor for the samples' amorphous content near the crystal edge and applied to the DSC data to improve the accuracy of the result, 42.9 ± 2.0 J/g.
- Analysis of gas sorption in glassy polymers with the GAB model: An alternative to the dual mode sorption model
Ondřej Vopička and Karel Friess
Article first published online: 11 SEP 2014 | DOI: 10.1002/polb.23588
Adsorption isotherms of carbon dioxide in cellulose acetate, polyethylene terephtalate, and the first polymer of intrinsic microporosity are analyzed by using the Guggenheim–Anderson–De Boer (GAB) model of multilayer adsorption. The GAB model provides a comparable quality of fit as the classical Dual Mode Sorption model. The analysis of the isosteric heat of adsorption supports the purely adsorptive mechanism, thus providing a new insight into the adsorption of gases in polymers.
