Inorganic polymers are polymers with a skeletal structure that does not include carbon atoms.[1] Polymers containing inorganic and organic components are named hybrid polymers.[2] One of the best known examples is polydimethylsiloxane, otherwise known commonly as silicone rubber. It has a repeat unit based on silicon and oxygen:


Silicon and oxygen also occur widely in a range of inorganic minerals, including silica, mica and feldspar with other elements.

The inorganic sulfur-nitrogen polymer polythiazyl, (SN)x, is, highly unusual, a metallic superconducting polymer below 0.26 K.[3]

Inorganic polymers with tunable or responsive properties are called smart inorganic polymers. A special class of inorganic polymers are geopolymers which my be anthropogenic or naturally occurring.



Inorganic polymers are formed, like organic polymers, by:
