In this report, both the structure-based and source-based nomenclature rules are extended to regular double-strand (ladder and spiro) organic polymers. Biopolymers, however, such as DNA are not considered here. Rules for quasi-single-strand coordination polymers, resembling spiro polymers yet not covalently bonded, are not included.

A regular linear polymer that can be described by a preferred CRU in which only one terminal constituent subunit is connected through a single atom to the other identical CRU is a quasi-single-strand polymer. Such polymers are named similarly to single-strand coordination polymers.

In the following sections, we will show how we can find these relations from X-ray diffraction measurements. As we have just explained, in order for relations of this type to make sense, the crystals in the film must all be oriented the same way, which means that the film is a quasi-single crystal . As a result, the relevant techniques and vocabulary are often taken from single crystal diffraction. 

We will see later on that we can determine the relative disorientation of the crystals in these films. It is often greater, hy about a few tenths of a degree, than disorientations between the domains of a single crystal. Therefore, the phrase quasi-single crystal should be used with care.
