Sentence examples for main chain motion from inspiring English sources

The main chain motion of lignin is observed in the whole CL/OH ratio.

The increase may be interpreted by the acceleration of main chain motion by lowering of Tg with increasing the content of the lower Tg component (PVDF).

Increasing further the PVDF content, the specific interaction seems to restrict the main chain motion and prevails over the Tg effect so that the peak appears in the fmax /gf) curve.

In the present work, we report results from two materials, polysulfone (PSF) and polycarbonate (PC), with weak β-relaxations that are due to main chain motions.

A study on the temperature dependence revealed two relaxation modes, one being the β-relaxation due to local motions in the side chain and the other being the α-relaxation due to the main- chain motions.

Comparing the temperature dependence of σdc and the relaxation frequencies of these processes, we conclude that the main-chain motion governs σdc through the dissociation of metal ions at low temperatures and spatial heterogeneity as well as the side-chain motion governs the ionic mobility at high temperatures.

The segmental main-chain motions were represented by the Dejean-Lauprêtre-Monnerie orientation autocorrelation function.

It was carried out in terms of relatively slow segmental main-chain motions and faster internal motions of the aromatic rings.

Interpretation of the 13C spin-lattice relaxation times in terms of segmental main-chain motions was carried out using the Dejean-Lauprêtre-Monnerie orientation autocorrelation function.

Although some main-chain motions may already be involved in the relaxations at lower temperatures, they fully account for the α relaxation observed around 120°C.

The fact that only one mode assigned to main-chain motions was detectable for CN-DPMA forms an interesting contrast to CN-DHPC, which shows two main-chain relaxation modes.
