cardo polymer

https://doi.org/10.1351/goldbook.15309
Polymer composed of macromolecules consisting of a single-strand main chain and many ring units, each having one atom in common with the main chain.
Notes:
  1. A cardo polymer can be represented graphically as follows:
    cardo polymer
  2. A cardo polymer can also be defined as a polymer composed of macromolecules containing loop-like cyclic side groups, one ring atom of which is part of the backbone.
  3. The adjective "cardo" is derived from the Latin word for heart because the cyclic unit, together with adjacent parts of the main chain, resembles the shape of a heart with arteries.
Example:
