Need help with polymer naming
« on: March 13, 2012, 04:21:05 AM »
Whats the chemical name of Silicone, I think its polysiloxane.. but I don't know.. I cant find any info that specifically says this.. And what is Silicones monomer? please answer!

There is no one silicone, this is a general name of a family of polymers.

From wikipedia...

http://en.wikipedia.org/wiki/Silicone

Quote
More precisely called polymerized siloxanes or polysiloxanes, silicones are mixed inorganic-organic polymers with the chemical formula [R2SiO]n, where R is an organic group such as methyl, ethyl, or phenyl. These materials consist of an inorganic silicon-oxygen backbone (⋯-Si-O-Si-O-Si-O-⋯) with organic side groups attached to the silicon atoms, which are four-coordinate.
 
In some cases, organic side groups can be used to link two or more of these -Si-O- backbones together. 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. The second largest group of silicone materials is based on silicone resins, which are formed by branched and cage-like oligosiloxanes.
