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.
SBR is a mixed polymer, or copolymer, consisting of two different monomer units, styrene and butadiene, arranged randomly along the molecular chain.
Stripped to its essentials, the theory regards the arches as a kind of large "polymer," or molecular chain of a huge size, and uses statistical methods, familiar from the physics of gases and fluids, to estimate the odds that the grains will fall together in just that sort of polymer.
The term polymer refers to any long molecular chain made up of smaller chemical units, or monomers, which polymer chemists habitually compare to beads on a necklace or, when they're going out for a nice dinner, to pearls on a strand.
The periodicity is slightly larger than 2 × molecular chain length.
A TPU molecular chain is illustrated in Fig. 1b.
With the increase in salinity, the polymer molecular chain became compressed that it could not interweave with another polymer molecular chain.
In contrast, AgNWs with higher density respond slowly to molecular chain movement.
Such anisotropy in resistance might be related with charge transfer along the molecular chain.
Therefore, the gap in the dimer is as narrow as the molecular chain length.
