Inorganic polymers are polymers with a skeletal structure that does not include carbon atoms.〔http://goldbook.iupac.org/IT07515.html〕 Polymers containing inorganic and organic components are named hybrid polymers.〔http://goldbook.iupac.org/HT07556.html〕 One of the best known examples is polydimethylsiloxane, otherwise known commonly as silicone rubber. It has a repeat unit based on silicon and oxygen: —()''n''— 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. == Examples == * Homochain polymers with one kind of atom in the main chain: * * Silicon-silicon: polysilanes; precursors to fibrous silicon carbide * * Germanium-germanium: polygermanes * * Tin-tin: polystannanes * Heterochain polymers with more than one type of atom in the main chain, mostly two types of atoms alternate along the main chain, ranked by atomic weight of in-chain elements:〔Mark, J. E.; Allcock, H. R.; West, R. “Inorganic Polymers” Prentice Hall, Englewood, NJ: 1992. ISBN 0-13-465881-7.〕 * * Boron-nitrogen: polyborazylenes * * Silicon-oxygen: polysiloxanes like the polydimethylsiloxane (PDMS), polymethylhydrosiloxane (PMHS) and polydiphenylsiloxane * * Silicon-nitrogen: polysilazanes like perhydridopolysilazane PHPS * * Phosphorus-nitrogen: polyphosphazenes and their precursor the poly(dichlorophosphazene) * * Phosphorus-oxygen: polyphosphates, which occur naturally and are widely used commercially. * * Sulfur-nitrogen: polythiazyls * Sulfur: polysulfides 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Inorganic polymer」の詳細全文を読む スポンサード リンク
