Macrocyclic polyalkene homopolymers and copolymers can be formed and converted to macrocyclic polyalkanes or macrocyclic poly(alkane-co-alkene) upon hydrogenation or, when the macrocyclic polyalkene is reacted with an alkene in the presence of an olefin metathesis catalyst, to a macrocyclic poly(alkane-co-alkene) comprising vicinal —C(═CR2)—'s. Upon hydrogenation of a macrocyclic poly(alkane-co-alkene) comprising vicinal —C(═CR2)-'s, macrocyclic poly(alkane)s or poly(alkane-co-alkene)s with isolated —C(═CR2)- groups can be provided, depending on the degree of hydrogenation. The poly(alkane-co-alkene)s with isolated —C(═CR2)- units can be used to form poly(macrocyclic poly(alkane-co-alkene))s, poly(macrocyclic poly(alkane))s, and/or bi-, tri-, and/or multi-macrocyclic poly(alkane-co-alkene)s or bi-, tri-, and/or multi-macrocyclic poly(alkane)s.
