Silicones are synthetic organosilicon polymers containing repeated R2SiO units held by Si-O-Si linkages. These compounds have general formula (R2SiO)n where R=methyl or aryl group. Preparation When methyl chloride reacts with silicon in the presence of copper as a catalyst at 570 K , various types of methyl substituted chlorosilanes of formula CH3SiCl3 , … [Read more...] about Silicones
