Dynamics of a paradigmatic linear polymer: A proton field-cycling NMR relaxometry study on poly(ethylene-propylene)

Hofmann M.; Kresse B.; Heymann L.; Privalov A.; Willner L.; Fatkullin N.; Aksel N.; Fujara F.; Rössler E. (2016)

© 2016 American Chemical Society.The dynamics of melts of linear poly(ethylene-alt-propylene) (PEP) of different molar masses (M) is investigated by 1H field-cycling (FC) NMR relaxometry. Employing a commercial and a ...
Scaling analysis of the viscoelastic response of linear polymers

Mohamed F.; Flämig M.; Hofmann M.; Heymann L.; Willner L.; Fatkullin N.; Aksel N.; Rössler E. (2018)

© 2018 Author(s). Viscoelastic response in terms of the complex shear modulus G∗(ω) of the linear polymers poly(ethylene-alt-propylene), poly(isoprene), and poly(butadiene) is studied for molar masses (M) from 3k up to ...
Segmental Mean Square Displacement: Field-Cycling <sup>1</sup>H Relaxometry vs Neutron Scattering

Hofmann M.; Kresse B.; Privalov A.; Heymann L.; Willner L.; Aksel N.; Fatkullin N.; Fujara F.; Rössler E. (2016)

© 2016 American Chemical Society.Proton (1H) field-cycling (FC) NMR relaxometry is applied to monitor the crossover in the segmental subdiffusion from the Rouse to the constrained Rouse regime in an entangled linear polymer ...
