Basically what the title asks. By a "chain", I mean a structure where you have two or more ring polymers (polymers where the ends are joined to form a large circular/ring-shaped molecule; different from something like a benzene ring), which interlock like links in a chain.
I'm not able to find much information about ring polymers (seems DNA is the most documented instance of something similar, since it sometimes takes the form of a ring in bacteria/viruses). Would it be possible for this sort of chain to exist? I'm mostly just asking out of curiosity, since if it is possible, one could imagine fun things like rings of ring polymers and molecule-scale chainmail.
