context_page_description: Cardo polymers are a sub group of polymers where carbons in the backbone of the polymer chain are also incorporated into ring structures. These backbone carbons are quaternary centers. As such, the cyclic side group lies perpendicular to the plane of the polymer chain, creating a looping structure. These rings are bulky structures which sterically hinder the polymers and prevent them from packing tightly. They also restrict the rotational range of motion of the polymer chain, creating a rigid backbone. As a result of their unique structures, these polymers have notably high thermal stability and solubility. There have been recent advances made in the applications of cardo polymers to membranes used for gas separation and transport.
