Polymers composed of macromolecules containing tetrazine or hydrogenated tetrazine rings in the backbone (structure-based polymer class name):

Note:
A typical polytetrazine contains 1,2,4,5-tetrazine or hydrogenated 1,2,4,5-tetrazine rings since 1,2,3,4- as well as 1,2,3,5-tetrazine rings are unstable.
