Chemical structure of the silicone polydimethylsiloxane (PDMS)
Alfred Stock and Carl Somiesky examined the hydrolysis of dichlorosilane, a reaction that was proposed to initially give the monomer H2SiO:SiH2Cl2+H2O⟶H2SiO+2HCl
When the hydrolysis is performed by treating a solution of H2SiCl2 in benzene with water, the product was determined to have the approximate formula [H2SiO]6. Higher polymers were proposed to form with time.
Most polysiloxanes feature organic substituents, e.g., [(CH3)2SiO]n and [(C6H5)2SiO)].
All polymerized siloxanes or polysiloxanes, silicones consist of an inorganic silicon–oxygen backbone chain (···−Si−O−Si−O−Si−O−···) with two groups attached to each silicon center. The materials can be cyclic or polymeric. By varying the −Si−O− chain lengths, side groups, and crosslinking, silicones can be synthesized with a wide variety of properties and compositions. They can vary in consistency from liquid to gel to rubber to hard plastic. The most common siloxane is linear polydimethylsiloxane (PDMS), a silicone oil.[citation needed] The second-largest group of silicone materials is based on silicone resins, which are formed by branched and cage-like oligosiloxanes.[citation needed]
