DEFINITION
Classification: 428/447
(under subclass 446) Product in which the silicon comprises (1) a compound similar to hydrocarbons in which the tetravalent silicon replaces the carbon atom, as Si H4 monosilane or silicomethane, (2) an elastomeric in which the carbon linkages of a polymerized hydrocarbon are replaced by Si-O linkages, or (3) any of a class of compounds that contain alternate silicon and oxygen atoms in either a linear structure (such as H3Si(O Si H2)nO Si H3 ) or a cyclic structure as H2(Si O)n and that may also contain methyl, phenyl or other organic radicals in place of some or all of the hydrogen atoms and are made by hydrolysis of chlorosilanes or alkoxy-silanes.
