The contorted structure and the hindered rotation of the polymer backbone generate inefficient chain packing, which leads to an increase of nanoporosity and higher surface areas.
Increasing T towards Tm brings about an enhanced asymmetry in the C C H valency angles and a small rotation of the polymer chains with a concomitant expansion of the interchain contacts lying approximately in the bc-plane.
The specific rotation of the polymers was found to vary in a non-linear manner with the proportion of chiral monomer incorporated into the polymers.
This could be envisaged as requiring a 180° rotation of every other polymer about its principal axis.
The increasing specific rotations of the polymers from acetate to butyrate to benzoate with both catalysts is explained by increasing substituent group size.
Support is given to the existence of conditions which lead to restricted molecular dipole rotation of water within a polymer network and a resulting "effective" relative permittivity of water based on polymer chemistry and morphology.
The lamellar long period (L) of the polymeric structure determined by small-angle X-ray scattering (SAXS) was found to increase upon the addition of nanoclay, which also resulted in variations in the angle of rotation between the polymer and clay lamellae.
Steady state polarization curves were carried out as a function of the rotation speed, the polymer thickness and the concentration of redox centers within the polymer.
