The Regular Single-Strand Polymers

Definition

Regular Polymers
     A polymer composed of regular macromolecules, i.e. macromolecules the structure of which essentially comprises the repetition of a single  constitutional unit with all units connected identically with respect to directional sense.

Single-Strand Polymer
     A polymer the macromolecules of which are single-strand macromolecules, i.e. macromolecules comprising constitutional units connected in such a way that adjacent constitutional units are joined to each other through two atoms, one of each constitutional unit.



Constitutional Unit
     An atom or group of atoms (with pendant atoms or groups ,if any) comprising a part of the essential structure of a macromolecule ,an oligomer molecule ,a block or a chain.

Constitutional Repeating Unit (CRU)
     The smallest constitution unit, the repetition of which constitutes aregular macromolecule, a regular oligomer molecule, a regular block or a regular chain.



Main Chain Backbone

     The linear chain to which all other chain, long or short or both, may be regarded as being pendant.

End-Group

     A constitutional unit that is an extremity of a macromolecule or oligomer molecule.

Seniority

     Priority in a set of atom or groups of atom accordding to a prescribed order.

Locant

     A numeral or letter that identifies position in a structure.
