multi-strand chain

in polymers
Also contains definition of: n-strand chain
https://doi.org/10.1351/goldbook.M04066
A chain that comprises constitutional units connected in such a way that adjacent constitutional units are joined to each other through more than four atoms, more than two on at least one side of each constitutional units.
Note:
A chain that comprises constitutional units joined to each other through \(n\) atoms on at least one side of each @C01288@ is termed an n-strand chain, e.g. three-strand chain. If an uncertainty exists in defining \(n\), the highest possible number is selected.
