[[Siloxane]]s are a premier example of an inorganic polymer, even though they have extensive organic substituents.  Their backbond is composed of alternating silicon and oxygen atoms, i.e. Si-O-Si-O...  The silicon atoms bear two substituents, usually [[methyl]] as in the case of [[polydimethylsiloxane]].  Some uncommon but illustrative inorganic polymers include [[polythiazyl]] ((SN)x) with alternating S and N atoms, and polyphosphates ((PO<sub>3</sub><sup>−</sup>)<sub>n</sub>).
