The larger negative deviation was interpreted to be a higher/greater contraction of free space and more tightly packing of molecular chains in TMBPS-PAr/PVC upon mixing irrespective of similar specific intermolecular interaction between two blend systems, which shows good agreement with the results of densities with blend compositions.
GPC analysis proved more homogeneous and longer PANi molecular chains can be generated by microwave-assisted in situ polymerization.
Furthermore, the addition of β-nucleating agent was beneficial for the molecular alignment during processing, the anisotropic particles of β-nucleating agent were much more effective to align the molecular chains in the flow direction compared to isotropic ones.
Decreasing the density decreases the crystallinity: the volume of crystallizing matter is lower and cell wholes become more and more thin, which decreases the mobility of the molecular chains.
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.
The oriented noncrystalline molecular chains could easily be reorganized into more perfect crystals in postheating runs.
Dispersive OVDs have lower molecular weight, shorter molecular chains and remain in the anterior chamber more than cohesive OVDs, requiring a longer aspiration time for their complete removal.
This explained that the cross-linking bonds between genipin and silk sericin would reduce the mobility of molecular chains within the films, resulting in the more rigid molecular structure.
With the further growing of molecular chains, the volume of polymer granules grows, and it becomes even more difficult to repeat the morphology completely.
Some art forms are more molecular than others.
