Therefore, these results lead to the conclusion that breaking intramolecular hydrogen bonds by increasing the substitution along the molecular chain causes it to become more flexible, which may account for the change in structural handedness.
The molecular chains in it adopt the planar zigzag conformation, which was only found in the sample under tension.
In principle, a polymer with higher molecular weight has, on average, longer molecular chains, and it will form more entanglements leading to a higher viscosity of the polymer solution.
With the increase in salinity, the polymer molecular chain became compressed that it could not interweave with another polymer molecular chain.
It was concluded that the molecular chain deformation of Ge-PEG-NHS likely occurred when large molecules were bound.
However, when the temperature plunged, the contraction of the molecular chain was too slow to restore to its original state, which was the reason cracks occurred.
It is ascribed that K30 has smaller molecular weight, shorter molecular chain length, and lower viscosity than K90, thus result in a weaker adsorption and induced effect in the process of assembly.
Each molecular chain that makes up the polymer contains one end that repels water and another that attracts water.
In 1983 Sauvage and collaborators created a molecular chain, [2]catenane.
The periodicity is slightly larger than 2 × molecular chain length.
